Best Americas-Asia Alliance Carriers (2026)

United's Star Alliance trans-Pacific JV with ANA and the partial JV with Singapore Airlines leads the 2026 Americas-Asia premium-cabin index on the strength of San Francisco, Los Angeles, and Newark gateway depth and the 787-9 and 787-10 deployment curve. ANA, Japan Airlines, and Delta with Korean Air follow, with American and Cathay Pacific holding the oneworld trans-Pacific structure together at narrower JV scope. Cirium schedules data shows total trans-Pacific premium-cabin capacity in Q2 2026 running roughly 87 percent of pre-pandemic baseline, with US-mainland China the lingering structural gap. Henry Harteveldt of Atmosphere Research describes the Pacific as 'a market where two of the three JVs are operating at structural maturity and the third — oneworld — is still working out whether American or Cathay is the gravitational center.'

The trans-Pacific is structurally the most asymmetric of the long-haul corridors. Three joint ventures with antitrust immunity — United with ANA inside the Star Alliance Pacific JV and a separate partial JV with Singapore Airlines, Delta with Korean Air inside SkyTeam, and American with Japan Airlines inside oneworld — now intermediate the bulk of scheduled premium-cabin capacity between the Americas and Asia, but the scope and operational integration of the three structures differ in ways that the transatlantic equivalents do not. Cirium schedule filings reconciled against US Department of Transportation T-100 data show approximately 87 percent of the Q2 2019 pre-pandemic premium-cabin baseline restored in the second quarter of 2026, with the residual 13 percent gap concentrated almost entirely in the US-mainland China sectors.

For corporate travel programs with material Asia-Pacific exposure, the practical consequence is that JV selection on the Pacific is meaningfully more route-specific than JV selection on the Atlantic. The US-Japan corridor is the densest and most JV-coordinated; the US-Korea corridor is anchored by a single immunized partnership; the US-China corridor remains in slow recovery and routes more often through third-country connecting hubs; the US-Southeast Asia and US-Taiwan corridors are anchored by Singapore Airlines and EVA Air respectively, with structurally different partner relationships. The Hawaiian Airlines integration into Alaska Air Group and the oneworld alliance adds a new variable for Pacific-anchored programs in 2026 that did not exist a year earlier.

This analysis ranks ten Americas-Asia carriers on their Q2 2026 premium-cabin capacity, schedule depth, JV positioning, product quality, and frequent flyer economics. Real carriers and real schedules only; Cirium, OAG, US DOT T-100, IATA, Skift Research, and named aviation analysts are the source base throughout.

What the Cirium and DOT capacity data shows

Cirium’s Diio Mi database, reconciled against US DOT T-100 international segment data and IATA Air Passenger Market analysis, shows approximately 96,000 weekly scheduled premium-cabin seats between Americas gateways and Asia-Pacific destinations in the second quarter of 2026. That figure is up roughly 6 percent year-over-year but remains approximately 13 percent below the Q2 2019 baseline. The composition has shifted decisively in three respects since 2019.

First, US-Japan capacity is now the dominant component of the trans-Pacific premium-cabin market, accounting for roughly 38 percent of total Americas-Asia scheduled premium seat-miles in Q2 2026 versus 31 percent in Q2 2019. The Tokyo Haneda slot reallocation of 2020 and the subsequent concentration of flagship aircraft on Haneda rotations by ANA, JAL, American, Delta, and United have made the US-Japan corridor the most JV-coordinated long-haul market in the Pacific.

Second, US-mainland China capacity is the persistent gap. Cirium-tracked Q2 2026 premium-cabin capacity between US gateways and Beijing, Shanghai, Guangzhou, and other mainland Chinese destinations sits at roughly 55 percent of the Q2 2019 baseline. The bilateral framework restoration has been incremental, and the corporate-travel patterns that established between 2020 and 2024 — connecting through Tokyo, Seoul, Hong Kong, or Taipei — have proven structurally sticky.

Third, Singapore Airlines’ US network has materially expanded. The carrier now operates daily-or-better service from New York JFK, Newark, Los Angeles, San Francisco, Seattle, and Houston Intercontinental, with the LAX-Singapore A350-900ULR rotation doubled to twice daily in March 2026. Cirium fleet data shows Singapore operating the most premium-dense widebody configuration of any trans-Pacific carrier on its ultra-long-haul US sectors.

Brian Pearce, formerly chief economist at IATA, framed the underlying trans-Pacific dynamics in his Q1 2026 commentary for the Centre for Aviation: “The Pacific recovery has been slower in aggregate than the Atlantic but more concentrated in premium yield. The carriers that have moved fastest on Haneda slot deployment, on 787 and A350 fleet rotation, and on JV-coordinated pricing are extracting premium-cabin unit revenue that is structurally above 2019 levels even with the China sectors still suppressed.”

Brian Sumers, in his March 2026 Airline Observer dispatch, made the procurement implication explicit: “If you are running an Asia-exposed corporate program and you have not re-examined your trans-Pacific panel since 2023, the Haneda concentration, the Singapore A350-900ULR doubling, the slow China recovery, and the Hawaiian-Alaska oneworld onboarding have all reshaped the right answer. The 2023 panel is not the 2026 panel.”

Methodology

Each of the ten carriers was scored against five weighted criteria.

Cirium-tracked weekly premium-cabin seat capacity (30 percent) — The sum of business and first class scheduled seats per week across all Americas-Asia nonstop routes operated on the carrier’s own metal in Q2 2026. Codeshare-only capacity carried on a partner’s metal was excluded; the JV partner that operates the flight gets the credit.

Schedule depth (20 percent) — Cirium-tracked count of Americas-Asia gateway pairs operated at daily-or-better frequency. Sub-daily and seasonal-only routes received partial credit. Schedule consistency through quarterly transitions was tracked as a contextual factor.

Alliance and JV positioning (20 percent) — Each carrier’s role inside its alliance and JV structure was assessed for revenue-share scope, antitrust-immunity coverage, partner network breadth, and lounge access across Asia-Pacific gateway hubs.

Premium-cabin product quality (15 percent) — Aircraft variants graded on lie-flat dimensions, suite-door availability, direct-aisle access, food and beverage program depth, and lounge access at primary trans-Pacific gateway hubs. The score is a weighted average across the carrier’s deployed Americas-Asia fleet.

Frequent flyer program economics (15 percent) — Partner-award math, dynamic pricing exposure, and corporate-account program flexibility through the carrier’s primary loyalty currency and JV-aligned partner programs.

Carriers were ranked by composite score. Figures cited in each profile are derived from Cirium schedule filings for Q2 2026 and rounded.

The ranked carriers

The capacity and share figures represent Q2 2026 scheduled seats and ASMs, sourced from Cirium Diio Mi and rounded. Actual flown capacity in any week will vary on equipment swaps and irregular operations.

1. United Airlines

United leads the 2026 Americas-Asia premium-cabin index on a combination of gateway depth, JV scope, and refleeting discipline. Cirium schedules data places United at approximately 15,800 weekly Polaris business class seats across the Pacific in Q2 2026, equal to roughly 16.5 percent of total Americas-Asia premium ASM share. San Francisco is the anchor gateway, with Los Angeles, Newark, Houston Intercontinental, Chicago O’Hare, and Washington Dulles rounding out the primary departure stack. Guam continues to operate as United’s secondary Pacific hub for intra-Asia connecting flows.

The Star Alliance Pacific joint venture with ANA, immunized by US DOT in 2011, is the broadest of the three trans-Pacific JVs by operational integration. The JV coordinates schedules, pricing, and revenue sharing across United and ANA trans-Pacific routes and is the structural reason United has been able to concentrate Polaris flying on Haneda slots without cannibalizing ANA’s parallel Haneda capacity. The separate partial joint venture with Singapore Airlines, focused specifically on US-Singapore routes, adds a second layer of immunized cooperation that no other US carrier replicates on the Pacific.

Polaris is deployed across the 787-9, 787-10, and post-2018 retrofit 777-300ER fleet. The cabin does not feature a closed suite door, which keeps it a notch below JAL’s Sky Suite Apex and Singapore’s 2024-refit business class on hardware, but the consistency of the product across United’s transpacific fleet is meaningfully better than the dispersed cabin standards at American on Pacific metal. The Polaris lounge network at SFO, LAX, EWR, ORD, IAH, and IAD is the strongest among US carriers on the Pacific.

MileagePlus has held up better than SkyMiles or AAdvantage on Pacific partner award redemption. Star Alliance partner awards on ANA, Singapore, EVA Air, Asiana, and Air Canada metal remain bookable on a recognizable chart structure, and Henry Harteveldt of Atmosphere Research has observed that “MileagePlus is the most useful US frequent flyer currency for Pacific premium redemption in 2026 — the partner award charts have held up substantially better than the own-metal dynamic pricing would suggest.”

2. ANA

ANA carries approximately 12,400 weekly Americas-Asia premium seats and 12.9 percent of premium ASM share. Tokyo Haneda is the dominant gateway with Tokyo Narita operating a secondary role, and Cirium-tracked schedules show daily-or-better ANA service from HND to JFK, EWR, IAD, ORD, LAX, SFO, SEA, IAH, and HNL, with NRT operating to LAX, SFO, ORD, and JFK. The Honolulu sector remains the carrier’s only scheduled A380 service worldwide, operating the Flying Honu liveried fleet on heavy-leisure rotations.

The carrier operates as the Asian anchor of the Star Alliance Pacific JV with United and is the most operationally integrated JV partner of any Asian carrier on the trans-Pacific. The Tokyo Haneda slot allocation has been coordinated with United’s HND rotations in a way that maximizes Star Alliance gateway coverage from both sides of the Pacific, and Bob Mann of R.W. Mann and Company has noted that the JV’s pricing and schedule alignment on Haneda routes is “the tightest commercial integration between a US and Asian carrier in commercial aviation.”

The 777-300ER fleet, with The Room business class and The Suite first class product, carries the flagship Pacific rotations. The Room is the analyst consensus choice for business class on the US-Tokyo corridor, featuring a fully closing suite door and one of the widest business-class beds in the industry. The 787-9 fleet operates the secondary Pacific rotations with a more standardized business class product. The A380 fleet operating Honolulu carries a unique premium-cabin configuration including Couchii double-bed seats and a refreshed first class.

ANA Mileage Club is well-regarded among Star Alliance frequent flyer programs but has limited utility for US-anchored corporate programs without a transferable points relationship. The American Express Membership Rewards transfer partnership remains the primary route for US-anchored travelers to access ANA’s first and business class award space.

3. Japan Airlines

Japan Airlines ranks third on the Americas-Asia premium-cabin index with approximately 11,200 weekly transpacific premium seats and 11.7 percent of premium ASM share. Tokyo Haneda is the anchor gateway with Narita operating secondary service. Cirium schedules show JAL operating daily-or-better Haneda service to JFK, BOS, LAX, SFO, ORD, DFW, SEA, and HNL, with Narita operating to LAX, SFO, JFK, DFW, BOS, and ORD.

JAL anchors the Asian side of the oneworld Pacific JV with American, immunized by US DOT in 2011. The JV is the most narrowly bilateral of the three trans-Pacific structures — American’s other oneworld Pacific relationships with Cathay Pacific and Qantas operate under alliance rather than JV terms — which has both advantages and limitations for corporate-account negotiation. The advantage is tighter American-JAL operational coordination on US-Japan routes; the limitation is that the JV does not extend to the broader oneworld Pacific network in the way A++ extends across the Lufthansa Group on the Atlantic.

The A350-1000 fleet, in active induction through 2025 and 2026 for trans-Pacific operations, carries the new Sky Suite Apex business class and Sky Suite I first class product. The cabin features fully closing suite doors and is the analyst consensus choice for premium hardware on the US-Japan corridor. The 787-9 fleet operates the secondary Pacific rotations with the Sky Suite III business class, and the 777-300ER fleet continues to operate with the earlier Sky Suite product pending retirement and replacement by additional A350-1000 deliveries through 2027.

JAL Mileage Bank is among the more useful Asian frequent flyer programs for US-anchored corporate travelers, with a partner award chart that has held up better than SkyMiles or AAdvantage own-metal redemption. The cross-program redemption through AAdvantage and through British Airways Executive Club Avios provides multiple efficient routes to JAL premium award space for oneworld-aligned travelers.

4. Delta Air Lines

Delta carries approximately 10,900 weekly Americas-Asia premium seats and 11.4 percent of premium ASM share. Seattle is the anchor Pacific gateway, with Los Angeles, Atlanta, Detroit, Minneapolis-St. Paul, and JFK rounding out the primary departure stack. Cirium-tracked schedules show daily-or-better Delta service from SEA to ICN, NRT, HND, and HKG, with SLC, LAX, MSP, DTW, and ATL operating to ICN as the carrier’s primary connecting hub on the Asian side.

The SkyTeam Pacific JV with Korean Air, granted antitrust immunity by US DOT in 2018, is the structural foundation of Delta’s Asia network. The JV is the second-largest trans-Pacific immunized structure by capacity and is built around a smaller partner roster than SkyTeam Atlantic — essentially a bilateral Delta-Korean Air integration rather than a multi-carrier coalition. The deliberate routing of Delta connecting flows through Incheon for onward intra-Asia service has functioned as the Pacific equivalent of Delta’s use of Heathrow via Virgin Atlantic on the Atlantic.

Delta One Suites on the A350-900 carry the premium product across the Pacific. The cabin features closed-door suites with direct-aisle access and is the analyst consensus choice for business class on the Seattle-Incheon and Detroit-Incheon rotations. The A330-900neo carries a competitive but less premium-dense business class product on secondary Pacific routes. The 767-400ER fleet, which previously operated some Pacific rotations, is now largely off the trans-Pacific network in favor of A330-900neo deployment.

SkyMiles redemption math remains the program’s persistent weakness, particularly on own-metal Pacific awards. The dynamic pricing decoupling has compressed SkyMiles transpacific premium value materially since 2019. However, Korean Air partner awards through SkyTeam remain bookable on a more transparent structure, and Korean’s SKYPASS program offers one of the better redemption value propositions for SkyTeam-aligned travelers seeking Pacific premium award space.

5. Korean Air

Korean Air carries approximately 9,400 weekly Americas-Asia premium seats and 9.8 percent of premium ASM share. Incheon is the single Asian gateway, and Cirium-tracked schedules show Korean Air operating daily-or-better service from ICN to JFK, EWR, BOS, IAD, ATL, MIA, ORD, DFW, IAH, LAX, SFO, SEA, LAS, HNL, YVR, YYZ, and Mexico City. The carrier’s Asian network depth from Incheon — with intra-Asia connections to Southeast Asia, China, Japan, and the broader Asia-Pacific — is the structural complement to Delta’s US gateway depth inside the SkyTeam Pacific JV.

The integration with the former Asiana Airlines, approved by Korean and EU regulators across 2023 and 2024 and operationally folding through 2025 and into 2026, has materially expanded Korean Air’s Asian network and intra-Asia premium seat capacity. Cirium fleet data shows the combined Korean Air-Asiana metal now operating roughly 65 percent of total ICN trans-Pacific premium ASMs, a structurally dominant position on the corridor.

The A350-900 fleet, in active induction through 2025 and 2026, is the new flagship for trans-Pacific operations and carries a refreshed business class with direct-aisle access and a competitive suite layout. The 787-9 fleet has expanded materially through 2024 and 2025 and carries a similar business class standard. The 777-300ER fleet continues to operate post-retrofit on heavy-demand Pacific sectors, with retirement curves indicating continued attrition through 2027 and 2028. The A380 fleet has been progressively retired since 2023.

SKYPASS, the Korean Air frequent flyer program, has historically offered one of the better partner award redemption structures in the SkyTeam family. The program is a Chase Ultimate Rewards transfer partner and an American Express Membership Rewards transfer partner, making it one of the more accessible Asian frequent flyer currencies for US-anchored travelers seeking Pacific premium award space through transferable points.

6. American Airlines

American carries approximately 7,600 weekly Americas-Asia premium seats and 7.9 percent of premium ASM share. Dallas-Fort Worth and Los Angeles are the anchor gateways, with JFK and Chicago O’Hare providing secondary depth. Cirium schedules show American operating daily-or-better Pacific service from DFW to HND and ICN, from LAX to HND, NRT, HKG, and SYD, from JFK to HND and HKG, and from ORD to HND. The carrier’s Pacific footprint is narrower than United’s or Delta’s by gateway count and by frequency density.

The oneworld Pacific JV with Japan Airlines, immunized in 2011, is the structural anchor. American’s other oneworld Pacific relationships — Cathay Pacific on Hong Kong-anchored routes, Qantas on Australia and New Zealand-anchored routes — operate under alliance terms rather than JV revenue sharing. This makes the American-JAL JV the most narrowly bilateral of the three immunized trans-Pacific structures, and Bob Mann has characterized the gap as “the reason oneworld is structurally less integrated on the Pacific than Star or SkyTeam — there’s no equivalent of A++ or the Delta-Korean structure that pulls the broader oneworld Pacific carriers into a single revenue-sharing entity.”

The Flagship Business Plus retrofit on the 777-300ER fleet has narrowed the product gap with JAL’s Sky Suite Apex and Cathay’s A350-1000 business class on Pacific rotations. The new cabin features a closed-door suite and direct-aisle access. The 787-9 fleet operates a complementary Flagship Business product without the closed door but with the same direct-aisle access standard. The 777-200ER fleet, with the older Flagship Business cabin, remains on secondary Pacific rotations pending continued retrofit progress and eventual retirement.

AAdvantage on Pacific partner awards through JAL Mileage Bank, Cathay Asia Miles, and Qantas Frequent Flyer remains among the more efficient redemption structures among the three US frequent flyer programs. The Avios pooling arrangement with British Airways, Iberia, Aer Lingus, and Finnair indirectly enables additional routing options for JAL and Cathay redemption through Executive Club Avios, which Henry Harteveldt has called “the most underappreciated cross-program redemption capability in US frequent flyer economics.”

7. Cathay Pacific

Cathay Pacific carries approximately 7,100 weekly Americas-Asia premium seats and 7.4 percent of premium ASM share. Hong Kong is the single Asian gateway, and Cirium-tracked schedules show Cathay operating daily-or-better service from HKG to JFK, EWR, BOS, LAX, SFO, ORD, IAD, YVR, YYZ, and Mexico City. The restoration of a full daily JFK-Hong Kong A350-1000 rotation in February 2026, after operating a sub-daily schedule through 2024 and 2025, has been the most-watched Pacific schedule addition of the past year.

The carrier operates as the trans-Pacific anchor of the oneworld alliance but does not participate in the American-JAL JV. This places Cathay in a structurally distinctive position — a fully-aligned oneworld member with antitrust-immune partnerships on intra-Asia routes but operating its trans-Pacific premium-cabin capacity under alliance terms rather than JV revenue sharing on the Pacific. The corporate-account implication is that Cathay metal does not automatically inherit American JV-aligned contracted-fare treatment, though oneworld lounge reciprocity and elite-status recognition apply.

The A350-1000 fleet carries the trans-Pacific flagship product with a closed-door business class suite and the refreshed first class on the heavy long-haul rotations. The A350-900 fleet operates secondary Pacific rotations with a competitive business class. The 777-300ER fleet, with the long-running but now-aging Business Plus cabin, remains on select rotations pending continued retirement and replacement by additional A350 and 777-9 inductions through the late 2020s.

Asia Miles, the Cathay frequent flyer program, has held up reasonably well for partner award redemption within oneworld. The program is a Chase Ultimate Rewards transfer partner and an American Express Membership Rewards transfer partner, providing US-anchored travelers a route to Cathay premium award space through transferable points. Brian Sumers has noted in his Airline Observer dispatches that “Cathay’s slow but visible 2026 capacity restoration on US routes is the most significant signal in oneworld Pacific in three years.”

8. Singapore Airlines

Singapore Airlines carries approximately 6,800 weekly Americas-Asia premium seats and 7.1 percent of premium ASM share. Singapore Changi is the anchor gateway, and Cirium schedules show Singapore operating daily-or-better service from SIN to JFK, EWR, LAX (twice daily after the March 2026 expansion), SFO, SEA, IAH, and YVR. The carrier’s US network now includes seven scheduled gateway pairs at daily-or-better frequency, the broadest US footprint of any Southeast Asian carrier.

Singapore is a full member of the Star Alliance and operates a partial joint venture with United on US-Singapore routes specifically. The partial JV is structurally narrower than the United-ANA Pacific JV but represents the only formal joint-venture relationship between a US and Southeast Asian carrier on the Pacific. The partial JV scope means Singapore retains greater independent commercial flexibility on US routes than ANA does inside the broader Star Alliance Pacific JV.

The A350-900 and A350-900ULR fleets carry the trans-Pacific premium product, with the ULR variant operating the EWR-Singapore and LAX-Singapore ultra-long-haul rotations as the world’s longest commercial flights. The 2024 business class refresh on the A350-900 fleet brought a new cabin standard with direct-aisle access and a competitive suite design, and Cirium fleet data shows Singapore operating the most premium-dense widebody configuration on the US-Singapore ULR routes — the EWR-SIN A350-900ULR carries no economy seats at all, configured as 67 business class and 94 premium economy.

KrisFlyer, the Singapore frequent flyer program, is a Chase Ultimate Rewards transfer partner, an American Express Membership Rewards transfer partner, and a Citi ThankYou Rewards transfer partner — the broadest transferable-points integration of any Asian frequent flyer currency. Singapore Suites on the A380 fleet (operating from select US gateways via Frankfurt and other connecting points) remains the analyst consensus choice for the highest-end premium cabin in commercial aviation, though direct US-Singapore service is A350-900 operated rather than A380.

9. EVA Air

EVA Air carries approximately 4,300 weekly Americas-Asia premium seats and 4.5 percent of premium ASM share. Taipei Taoyuan is the anchor Asian gateway, and Cirium-tracked schedules show EVA operating daily-or-better service from TPE to JFK, EWR, ORD, LAX, SFO, SEA, IAH, and YVR. The carrier’s US network depth — particularly from LAX, SFO, and SEA at multiple daily frequencies — gives it the most extensive US footprint of any Taiwanese or non-Japanese East Asian carrier.

EVA is a full member of the Star Alliance and does not operate a joint venture with any US carrier. The structural position is similar to that of EVA’s regional competitor China Airlines (a SkyTeam member without a trans-Pacific JV) but with materially deeper US gateway coverage and a more premium-tilted fleet deployment. The Taipei hub functions as a connecting gateway for intra-Asia premium flows, particularly to Southeast Asia and to mainland China sectors where direct US-China capacity has not fully restored.

The 787-9 and 787-10 fleets carry the trans-Pacific premium product with the Royal Laurel business class. The 777-300ER fleet, with an older but still competitive Royal Laurel business class, operates the secondary Pacific rotations. EVA’s business class hardware is among the more highly rated in Star Alliance Pacific operations, with the 787 reverse-herringbone configuration delivering competitive lie-flat dimensions and direct-aisle access.

Infinity MileageLands, the EVA frequent flyer program, is not a major transferable-points partner for US programs, which limits its standalone appeal for US-anchored travelers. However, EVA partner award redemption through United MileagePlus and through Aeroplan provides the more practical route to EVA premium award space for Star Alliance-aligned travelers, and Aeroplan in particular has offered some of the more efficient cents-per-mile redemption rates on EVA Pacific metal.

10. Hawaiian Airlines

Hawaiian Airlines carries approximately 1,500 weekly Americas-Asia premium seats and 1.6 percent of premium ASM share — the smallest share among the ten carriers in this analysis but with a structurally distinctive position after the Alaska Air Group acquisition closed in late 2024. Cirium schedules show Hawaiian operating from Honolulu to Tokyo Haneda, Seoul Incheon, Sydney, and Auckland, with Honolulu-Tokyo Narita and select Tahiti and Pacific Island routes operating at lower frequency.

The Alaska acquisition is rolling Hawaiian into the oneworld alliance through a phased onboarding that began in early 2025 and continues through 2026. The integration has materially improved Hawaiian’s distribution reach for corporate panels — the carrier now appears in oneworld code-share and award-search structures alongside American, JAL, Cathay, and Qantas — but Hawaiian does not participate in the American-JAL Pacific JV. The structural position is similar to that of Aer Lingus inside the AAA Atlantic JV: an alliance member with partial corporate-account integration but without full revenue-sharing JV participation.

The 787-9 fleet, in induction through 2025 and 2026, carries the new Leihoku Suites business class with a closed-door suite design and direct-aisle access. Cirium fleet data shows Hawaiian’s 787-9 deployment focused on the longer Pacific rotations (HNL-HND, HNL-ICN, HNL-SYD, HNL-AKL) with the A330-200 fleet operating shorter Pacific and US-Hawaii routes. The A330-200 fleet carries an older lie-flat business class without a closed suite door.

HawaiianMiles, the Hawaiian frequent flyer program, is integrating with Alaska Mileage Plan through 2026 in a process that will eventually consolidate the two currencies. For US-anchored corporate programs, the integration with Alaska’s distribution and Alaska’s existing oneworld onboarding has been the most consequential change — Hawaiian’s Pacific metal is now bookable and recognizable inside an Alaska-anchored or oneworld-aligned corporate panel in a way that was structurally difficult before the acquisition.

The trans-Pacific JV economics

The three immunized trans-Pacific JVs are structurally asymmetric, and the differences are economically material for corporate-account negotiation in 2026.

The Star Alliance Pacific JV — United and ANA — is the broadest and most operationally integrated. Antitrust immunity was granted by US DOT in 2011 and has functioned as the most tightly coordinated US-Asia commercial relationship since. The separate United-Singapore partial JV, focused specifically on US-Singapore routes, adds a second layer of immunized cooperation that no other US carrier has replicated on the Pacific. Bob Mann has framed the structural position: “United is the only US carrier with two immunized Pacific JVs running simultaneously, and the breadth of that structure compounds at the corporate-account negotiation table.”

The SkyTeam Pacific JV — Delta and Korean Air — is the second-largest by capacity. Antitrust immunity was granted by US DOT in 2018, making it the newest of the three trans-Pacific JVs by years of operation. The structure is bilateral rather than multi-carrier and is built around the Incheon hub’s role as the SkyTeam Pacific connecting anchor. The Korean Air-Asiana merger integration has expanded the JV’s effective intra-Asia network depth substantially through 2025 and 2026.

The oneworld Pacific JV — American and Japan Airlines — is the most narrowly bilateral of the three. Antitrust immunity was granted in 2011, but the JV does not extend to American’s other oneworld Pacific partners (Cathay Pacific, Qantas) under JV revenue sharing — those operate under alliance terms only. Henry Harteveldt has framed the structural gap: “On the Atlantic, oneworld has the AAA JV pulling four carriers into a single revenue-sharing entity. On the Pacific, oneworld has the American-JAL bilateral and an alliance relationship with Cathay. The procurement economics are not the same.”

The revenue-sharing economics on the Pacific JVs follow patterns broadly similar to the Atlantic equivalents: the carrier operating a particular metal segment may not be the carrier capturing the largest share of the segment’s profit, and JV-level rather than carrier-level negotiation has become the structurally correct approach for corporate-account sourcing. Where the Pacific differs is in the narrower JV scope: a Delta-anchored Pacific panel inherits Korean Air but not the broader SkyTeam Asian network on JV terms; an American-anchored Pacific panel inherits JAL but not Cathay or Qantas on JV terms.

US-mainland China capacity and the third-country routing pattern

The slow restoration of US-mainland China capacity is the structural anomaly of the 2026 trans-Pacific premium-cabin market. Cirium-tracked Q2 2026 scheduled premium-cabin seats between US gateways and mainland China — Beijing, Shanghai, Guangzhou, and other destinations — sit at approximately 55 percent of the Q2 2019 baseline. The bilateral US-China air services framework restoration has been incremental, with US DOT and CAAC announcing incremental frequency expansions across 2024, 2025, and the first half of 2026 that have yet to fully close the gap.

Air China, China Eastern, and China Southern operate the bulk of restored mainland-Chinese trans-Pacific capacity, but at frequency densities and premium-cabin counts well below 2019 levels. None of the three mainland carriers participates in an immunized JV with a US partner — Air China is a Star Alliance member, China Eastern and China Southern are SkyTeam members through legacy alliance affiliations — and the lack of JV coordination has compounded the slow capacity restoration. United, Delta, and American operate residual scheduled service to Beijing, Shanghai, and Hong Kong respectively, but at materially reduced frequency relative to 2019.

The corporate-travel pattern that has established between 2020 and 2026 routes mainland-China premium demand through third-country connecting hubs — Tokyo Haneda and Narita, Seoul Incheon, Hong Kong, Taipei Taoyuan, and Singapore Changi. ANA, JAL, Korean Air, Cathay Pacific, EVA Air, and Singapore Airlines have collectively absorbed substantial US-China premium-cabin demand through these routings, and Brian Sumers has noted that “the third-country routing pattern is proving structurally sticky even as direct frequencies recover — the corporate-travel program that established a Tokyo or Seoul connecting hub in 2021 has institutionalized that routing and is not rapidly switching back to direct.”

For 2026 corporate panels with material mainland-China exposure, the practical implication is that JV-aligned Tokyo, Seoul, and Hong Kong connecting routings should generally be preferred to non-aligned direct mainland-Chinese metal. The premium-cabin product gap and the corporate-account integration gap between, for example, JAL through Haneda versus China Eastern direct to Shanghai materially favor the JV-aligned routing for procurement panel construction.

Equipment deployment patterns

Cirium fleet data shows the 787-9, 787-10, and A350-900/A350-1000 families carrying a structurally increasing share of trans-Pacific premium ASMs through 2026. The 787-9 is the workhorse on United, JAL, EVA Air, and Hawaiian; the 787-10 is in growing deployment at United, Singapore, and EVA. The A350-900 anchors Delta, Korean Air, Singapore, and Cathay Pacific Pacific operations; the A350-1000 anchors JAL’s new flagship deployment and Cathay’s long-haul Pacific premium product.

The 777-300ER fleets across United (post-Polaris retrofit), American (post-Flagship Business Plus retrofit), ANA, JAL, Korean Air, Cathay Pacific, EVA Air, and Singapore Airlines continue to operate post-retrofit with competitive premium cabins on heavy-demand Pacific sectors. The pre-retrofit 777-200ER capacity at American and the older A330 capacity at select carriers represent the lingering equipment-quality gap on the Pacific, with retirement curves indicating continued attrition through 2027 and 2028.

The A380 fleet has materially contracted on the Pacific since 2019. Korean Air has retired its A380 fleet; Singapore Airlines operates the A380 selectively on Pacific routes via Frankfurt connections rather than direct US service; ANA continues to operate the A380 only on Honolulu rotations. The 747-8 has never operated trans-Pacific in commercial passenger service.

For corporate-travel programs, the equipment-quality variable matters most on the routes where multiple carriers compete. JFK-Haneda, LAX-Haneda, SFO-Haneda, LAX-Hong Kong, and LAX-Singapore are the corridors where the cabin-product gap between carriers can shift preferred-airline weighting at the margin, and Cirium’s twelve-month forward schedules are the relevant data source for assessing which metal is actually deployed on which rotation.

Hawaiian-Alaska integration impact

The Alaska Air Group acquisition of Hawaiian Airlines, closed in late 2024 and operationally integrating through 2025 and 2026, has been the most consequential alliance development on the Pacific in three years. The integrated network now operates inside the oneworld alliance — Alaska joined oneworld in 2021, and Hawaiian’s phased onboarding began in early 2025 — and the combined route map gives oneworld materially deeper Pacific coverage from US west-coast gateways than American alone could provide.

The procurement implication is that an oneworld-anchored corporate panel now includes Hawaiian’s Honolulu hub as a structural asset rather than a stranded carrier. Hawaiian’s Tokyo Haneda, Seoul Incheon, Sydney, and Auckland rotations from Honolulu, combined with Alaska’s domestic US west-coast network and American’s JAL JV, give oneworld a more coherent Pacific premium-cabin proposition than existed before the acquisition. Bob Mann has framed the change: “The Hawaiian-Alaska integration is the first material expansion of oneworld Pacific scope in a decade. It does not change the JV structure, but it changes the alliance-level footprint in ways that matter for west-coast corporate programs.”

The structural limitation remains that Hawaiian does not participate in the American-JAL JV. Hawaiian metal is bookable inside oneworld but does not inherit JV-aligned contracted-fare treatment. For corporate panels, the practical pattern is that Hawaiian operates as a complementary alliance asset for Pacific-anchored programs rather than a JV-level structural partner.

Takeaways for 2026-2027 procurement panels

Four patterns emerge from the Cirium and US DOT data and align with the analyst consensus from Harteveldt, Mann, Pearce, and Sumers.

First, JV asymmetry matters more on the Pacific than on the Atlantic. The three trans-Pacific JVs are not equivalent in scope or operational integration. The Star Alliance Pacific JV with the United-ANA structure and the parallel United-Singapore partial JV is the broadest; the SkyTeam Pacific JV is bilateral but operationally mature; the oneworld Pacific JV is narrowly bilateral and does not extend to Cathay or Qantas under JV terms. Corporate panel construction has to account for this asymmetry in a way that Atlantic panel construction does not.

Second, the Haneda concentration is the dominant single procurement variable. Tokyo Haneda’s slot allocation, frequency density, and concentration of flagship aircraft across ANA, JAL, American, Delta, and United have made the US-Japan corridor the most JV-coordinated long-haul market in the Pacific. Corporate panels with material Japan exposure are effectively choosing between three JV-aligned Haneda routings, and the carrier-level choice follows from the JV decision and from the program’s US gateway anchor.

Third, US-mainland China remains a third-country routing market. The slow direct-frequency restoration on US-China sectors, combined with the absence of JV coordination among mainland Chinese carriers and US partners, has institutionalized the Tokyo, Seoul, Hong Kong, Taipei, and Singapore connecting patterns. Procurement panels with material China exposure should structure their preferred-carrier weighting around the JV-aligned connecting hubs rather than around residual direct mainland-Chinese service.

Fourth, the Hawaiian-Alaska integration adds a fourth procurement variable. The expanded oneworld Pacific footprint from US west-coast and Honolulu gateways gives oneworld a more coherent alliance-level Pacific proposition, even without extending the American-JAL JV to include Hawaiian. Pacific-anchored programs and west-coast-anchored programs should reassess their oneworld weighting in light of the integration.

For a corporate program building a 2026-2027 preferred-airline panel on the Pacific, the practical implication is that the JV-level structural decision drives the carrier-level implementation, and the JV-level structures themselves are meaningfully more asymmetric than on the Atlantic. The procurement complexity is higher; the optionality between JVs is narrower on a per-corridor basis; and the equipment, gateway, and connecting-hub variables compound in ways that reward data-driven panel construction.

Comparison summary

The trans-Pacific is not a market that rewards procurement-panel improvisation in 2026. The data discipline that Cirium and US DOT make available, the JV-level structural asymmetries that Mann and Sumers have documented, the slow mainland-China capacity restoration that Pearce has tracked, and the Hawaiian-Alaska oneworld onboarding that has expanded alliance-level Pacific scope all point to a market that is meaningfully more complex than the Atlantic equivalent. The three-JV structure is the operating system, but the JVs themselves are asymmetric, and the carrier-level implementation has to account for that asymmetry in a way that transatlantic panel construction does not. The procurement implications follow from there.
