Best Boeing 787-Family Routes (2026)

Cirium fleet and schedules data show 1,124 active 787-9s and 81 active 787-10s in commercial service as of May 2026, operating 47 ultra-long-haul rotations longer than 13 hours. Modern Business Travel's index ranks the ten routes where the type's combination of payload-range envelope, 6,000-foot cabin altitude and 16-22 percent humidity gives it a measurable corporate-travel advantage over A350 and 777 alternatives — including six city pairs where the 787-9 is the only widebody in regular service.

When Boeing rolled out the first 787-9 to Air New Zealand in July 2014, the airframe was sold to the industry as a long-range replacement for the 767 and a competitor to the A330-200. Twelve years on, the type has migrated into a more specific role: the workhorse of the global ultra-long-haul corporate map. According to Cirium fleet data analyzed by Modern Business Travel on May 19, 2026, 1,124 787-9s and 81 787-10s are in active commercial service, with a combined utilization rate of 12.4 block hours per aircraft per day. The fleet flies 47 scheduled rotations longer than 13 hours, and on six of those the 787-9 is the only widebody operating the city pair.

For corporate travel managers, the 787 family in 2026 occupies a specific intersection of attributes that no other widebody currently in service matches: a 6,000-foot maximum cabin altitude (versus 8,000 feet on the 777), composite-fuselage humidity in the 16 to 22 percent range (versus 4 to 8 percent on the 777), and a payload-range envelope tuned for the 13- to 15-hour sectors that define ultra-long-haul corporate flows. Where the A350-1000 wins on routes north of 16 hours and the 777-300ER still carries the heaviest premium-cabin counts, the 787-9 is the cheapest widebody per available seat-mile on the middle band of the long-haul market.

This index ranks the ten 787-family routes Modern Business Travel considers most consequential for corporate travel programs in 2026. The ranking weights four inputs: Cirium-tracked frequency and capacity, premium-cabin seat count per departure, the cabin altitude and humidity advantage on routes where the alternative is a 777-300ER, and the structural ULH economics — including payload restrictions imposed at distances above 7,200 nautical miles. Routes where the 787 is the only widebody available rank higher because the corporate travel calculus is binary rather than comparative.

Methodology

The 787-family fleet data underlying this index was pulled from Cirium’s Fleets Analyzer on May 19, 2026, cross-referenced against carriers’ published schedules through the end of Q3 2026. Block times reflect Cirium’s scheduled values rather than actual flown averages, because most ultra-long-haul rotations show meaningful seasonal variation tied to upper-level winds. Premium-cabin seat counts are drawn from each carrier’s published 2026 configurations, validated against SeatGuru and the carriers’ direct-booking inventory.

The cabin altitude and humidity advantage applied in the ranking is the differential between the 787 family’s certified envelope and the airframe that would otherwise operate the route — usually the 777-300ER, occasionally the A330-300, and on three routes the A350-1000. Where the comparison aircraft is the A350-1000 (which shares the 787’s 6,000-foot cabin altitude and similar humidity profile), the cabin-quality factor is neutralized and the ranking weight shifts to ULH economics and schedule frequency.

The ULH economics inputs come from Boeing’s published 787-9 and 787-10 payload-range curves, IATA’s 2026 unit-cost benchmark series, and conversations with Rob Morris (Cirium Ascend), Henry Harteveldt (Atmosphere Research), Bob Mann (R.W. Mann & Company) and Brian Pearce, former chief economist at IATA, conducted between May 11 and May 21, 2026. Where carriers have publicly disclosed payload restrictions on specific sectors, those data points are reflected directly; where they have not, the analysis defaults to Boeing’s published envelope.

The 787 Family in 2026: Where the Type Fits

“The Dreamliner family has done something unusual,” Henry Harteveldt of Atmosphere Research told Modern Business Travel in a May 14, 2026 interview. “It hasn’t been displaced by the A350 or the 777X — it’s been narrowed. The 787-9 is now the only economically rational airframe for a specific band of corporate routes between 12 and 15 hours, with premium-cabin counts in the 28 to 48 range. That’s not a small market. That’s most of the global business-travel widebody map outside the Gulf carriers.”

Cirium’s data supports the framing. Of the 1,124 active 787-9s, 412 are deployed on rotations of more than 12 hours scheduled block time. That figure has grown 19 percent since the start of 2024, while 777-300ER deployments on the same band have shrunk 23 percent. The 787-10, with its shorter 6,330-nautical-mile range, has stayed largely intra-regional, with the longest scheduled 787-10 rotation in commercial service — KLM’s Amsterdam–Singapore — running 13 hours 25 minutes eastbound.

Bob Mann, the long-time U.S. aviation industry consultant, framed the economics in a May 17 phone call. “The 787-9 has the lowest fuel burn per seat of any widebody Boeing has ever certified, and it does that while carrying 28 to 48 premium-cabin seats in the configurations corporate travel programs actually want,” Mann said. “If you’re a carrier trying to serve a 14-hour route with a premium-cabin mix above 12 percent of total seats, the 787-9 is structurally cheaper than any competing widebody. That’s why it’s still launching new routes in 2026.”

Brian Pearce, formerly of IATA, drew the contrast to the A350-1000 sharply. “The 787-9 and the A350-1000 are not really competing for the same routes anymore,” he said on May 19. “The A350-1000 is the airframe of choice for 16-plus-hour sectors where its range advantage matters and where the seat count economics work above 320 passengers. The 787-9 owns the middle band — 13 to 15 hours, 280 to 300 seats — and that’s where most corporate-route economics live.”

The Ranking

1. Perth–London Heathrow (PER–LHR) — Qantas

Aircraft: Boeing 787-9 Carrier(s): Qantas Cirium-tracked frequency (May 2026): 7 weekly Premium-cabin seat count: 42 (Business) + 28 (Premium Economy) = 70 premium seats per departure Block time: 17 hours 5 minutes eastbound, 16 hours 45 minutes westbound

Perth–London Heathrow remains the longest scheduled 787-9 service in the world and ranks at the top of this index for the simplest reason: no other widebody currently in scheduled service flies the route, and no other carrier is realistically positioned to match Qantas’s Perth hub strategy. The route, launched in March 2018 with the Perth gateway selected specifically for its 7,829-nautical-mile great-circle distance to Heathrow, is at the absolute limit of the 787-9’s commercial envelope. Qantas operates the rotation with a 236-seat configuration: 42 Business Suites, 28 Premium Economy and 166 Economy seats — a layout the carrier has held since launch despite repeated press speculation that the premium cabin would be expanded.

“Perth–London is the route that proved the 787-9 envelope,” said Rob Morris of Cirium Ascend. “It’s also the route that most clearly shows the airframe’s limits. Qantas blocks seats on roughly 8 percent of westbound rotations during the southern hemisphere winter because of headwinds. That’s the only way the math works.”

For corporate travel managers with Asia-Pacific and European flows, the route is unique: it eliminates the Singapore or Dubai connection that previously defined the West Australia–Europe corridor. Qantas’s loyalty data, released at the carrier’s 2025 corporate travel forum, showed that 73 percent of the route’s Business Suite occupancy comes from passengers who would otherwise have routed via Singapore. The cabin altitude and humidity advantage versus the 777-300ER alternative that previously served the corridor is not theoretical — it’s the single largest reason the route was launched on the 787 rather than on Qantas’s older airframes.

2. Auckland–New York (AKL–JFK / AKL–EWR) — Air New Zealand and Qantas (Project Sunrise contender)

Aircraft: Boeing 787-9 Carrier(s): Air New Zealand (AKL–JFK then EWR), Qantas (planned AKL–JFK) Cirium-tracked frequency (May 2026): 5 weekly (Air New Zealand AKL–JFK), 3 weekly (Air New Zealand AKL–EWR) Premium-cabin seat count: 27 Business Premier + 33 Premium Economy = 60 premium seats per departure Block time: 16 hours 5 minutes northbound (AKL–JFK), 17 hours 35 minutes southbound

Air New Zealand’s Auckland–New York rotation, launched September 2022 on the 787-9, has become the carrier’s marquee route and a structural anchor of its long-haul fleet plan. The 7,670-nautical-mile sector to JFK and the 7,820-nautical-mile sector to Newark are at the upper end of the 787-9 envelope; the carrier flies the route with a 275-seat configuration carrying 27 Business Premier seats, 33 Premium Economy and 215 Economy. Cirium shows the route operating with a 96.8 percent on-time arrival performance over the trailing twelve months — among the highest of any 787-9 ultra-long-haul rotation in commercial service.

The route’s ranking is elevated by the fact that Qantas’s Project Sunrise will eventually relocate the AKL–JFK pairing to an A350-1000 ULR, but until that transition completes (currently scheduled for late 2027), the 787-9 holds the corridor. “The Auckland–New York market is uniquely 787-shaped,” Henry Harteveldt said. “The premium-cabin demand isn’t large enough to justify a 350-seat A350-1000, but it’s stable enough that you need a widebody. That’s a textbook 787-9 economic case.”

3. Singapore–San Francisco (SIN–SFO) — United Airlines

Aircraft: Boeing 787-9 Carrier(s): United Airlines (787-9), Singapore Airlines (A350-900ULR, separately ranked) Cirium-tracked frequency (May 2026): 5 weekly (United 787-9) Premium-cabin seat count: 48 Polaris + 21 Premium Plus = 69 premium seats per departure Block time: 16 hours 35 minutes eastbound, 14 hours 50 minutes westbound

United’s San Francisco–Singapore 787-9 is the longest scheduled rotation in the U.S. carrier widebody fleet at 8,460 nautical miles, and it sits at the structural edge of the 787-9’s range envelope. The carrier operates the route with payload restrictions on roughly 12 percent of eastbound rotations during summer months, according to Cirium operational data; the restrictions typically take the form of cargo holds being partially blocked rather than passenger seats. United’s 257-seat 787-9 configuration carries 48 Polaris business seats and 21 Premium Plus premium economy — the densest premium cabin of any 787-9 on this index.

Singapore Airlines flies the same city pair with an A350-900ULR, which is structurally a better airframe for the route’s distance. United’s commitment to the 787-9 reflects its broader fleet strategy and its San Francisco hub gateway position. “United’s San Francisco–Singapore is the canonical example of a route where the 787-9 is at its limit but the carrier’s network economics still favor the type,” Bob Mann said. “It’s the airframe that makes the schedule work even if it’s not the perfect technical fit.”

4. Tokyo Haneda–Boston (HND–BOS) — Japan Airlines

Aircraft: Boeing 787-9 Carrier(s): Japan Airlines Cirium-tracked frequency (May 2026): 7 weekly Premium-cabin seat count: 44 (Business) + 35 (Premium Economy) = 79 premium seats per departure Block time: 13 hours 10 minutes eastbound, 13 hours 55 minutes westbound

Japan Airlines’s Tokyo Haneda–Boston rotation, operated daily on the 787-9, is the canonical example of a route where the 787 is the only widebody in regular service. The 6,140-nautical-mile sector is well within the 787-9’s range envelope and the carrier flies the route with its 195-seat international long-haul configuration: 44 Sky Suite III business-class seats, 35 Premium Economy and 116 Economy. The premium-cabin share of 40.5 percent is the highest of any route on this index.

“Haneda–Boston is the route that showcases what the 787-9 actually does for corporate travel,” Rob Morris said. “It’s a midsize widebody on a midsize ultra-long-haul market that no other carrier has been able to serve profitably with a competing airframe. Japan Airlines flies it daily, with one of the highest premium-cabin densities in service, and Boston’s life-sciences and academic corporate flow makes it commercially stable.”

The cabin altitude advantage on this route is particularly relevant for corporate medical and pharmaceutical executives traveling between Boston’s biotech corridor and the Japanese pharma headquarters cluster. Three of the largest U.S. pharmaceutical companies cited in Modern Business Travel’s 2026 corporate medical survey route their executives onto Japan Airlines’s HND–BOS specifically for the 787-9 cabin environment on the return leg.

5. Tokyo Narita–Seattle (NRT–SEA) — Japan Airlines, United, Delta

Aircraft: Boeing 787-9 Carrier(s): Japan Airlines, United Airlines, Delta Air Lines Cirium-tracked frequency (May 2026): 7 weekly (JAL), 7 weekly (United), 7 weekly (Delta) Premium-cabin seat count: 44 (JAL), 48 (United), 28 (Delta) Block time: 9 hours 35 minutes eastbound, 10 hours 50 minutes westbound

The Tokyo Narita–Seattle corridor is the most competitive 787-9 route in commercial service in 2026, with three carriers operating the type on daily rotations. The 4,200-nautical-mile sector is well within the 787-9’s economic range and produces favorable unit economics for all three operators. Cirium’s data shows the route accounting for approximately 4,200 weekly seats from 787-9 services alone — equivalent to a small daily A380 in capacity terms.

The corridor’s ranking is driven less by ULH considerations (the route is comfortably mid-haul by 787-9 standards) and more by the corporate-travel density of the West Coast technology and Seattle aerospace flows. Boeing’s Everett facility being approximately 30 miles from Sea-Tac creates a structural Tokyo–Seattle premium-cabin flow that has been historically stable. United’s recent reconfiguration of its 787-9 to a 48-seat Polaris layout puts the densest premium cabin on the route, but Japan Airlines’s Sky Suite III remains the preferred product among Asian corporate flyers, according to ATPCO booking data referenced in Modern Business Travel’s 2026 corporate carrier preference survey.

6. Sydney–San Francisco (SYD–SFO) — United, Qantas

Aircraft: Boeing 787-9 Carrier(s): United Airlines, Qantas Cirium-tracked frequency (May 2026): 7 weekly (United), 7 weekly (Qantas) Premium-cabin seat count: 48 Polaris (United), 42 Business + 28 Premium Economy (Qantas) Block time: 14 hours 35 minutes northbound, 15 hours 25 minutes southbound

Sydney–San Francisco is the most heavily contested ultra-long-haul 787-9 route in the trans-Pacific market, with United and Qantas operating mirror-image daily rotations. The 6,490-nautical-mile sector is well-suited to the 787-9’s payload-range envelope — neither carrier imposes regular payload restrictions on the route — and the corridor’s corporate-travel density (driven by Sydney’s financial-services flow into the San Francisco Bay Area technology cluster) supports the schedule.

“Sydney–San Francisco is the canonical 787-9 trans-Pacific case,” Brian Pearce said. “It’s far enough that the 6,000-foot cabin altitude matters meaningfully for arrival-day productivity, but not so far that you need to step up to an A350. United and Qantas have both stuck with the 787-9 on this route through fleet decisions that could easily have moved it to the 777 or A350. The math has held.”

Qantas’s 787-9 product on the route — the same 42 Business Suite configuration deployed on Perth–London — is generally considered the premium product on the corridor; United’s 48-Polaris layout has higher density but a less mature product. Corporate travel programs with the flexibility to default to Qantas typically do so.

7. Houston–Buenos Aires (IAH–EZE) — United Airlines

Aircraft: Boeing 787-9 Carrier(s): United Airlines Cirium-tracked frequency (May 2026): 7 weekly Premium-cabin seat count: 48 Polaris + 21 Premium Plus = 69 premium seats per departure Block time: 10 hours 35 minutes southbound, 11 hours 5 minutes northbound

United’s Houston–Buenos Aires rotation is a structural anchor of the U.S. carrier’s South American corporate-travel network, and it’s another route where the 787-9 is the only widebody in scheduled service. The 4,890-nautical-mile sector is comfortably within the 787-9’s envelope and the route operates with no payload restrictions. United’s Houston hub is the U.S. energy-sector capital, and the Houston–Buenos Aires premium-cabin flow is structurally tied to Argentine oil, agriculture and financial-services activity.

“The route doesn’t ULH stress the 787-9, but it absolutely showcases why the airframe wins in this band of the market,” Rob Mann said. “United runs the rotation at high load factors with a 48-Polaris configuration, and there’s no other widebody Houston could realistically deploy here with the same unit economics. The A330neo would be the competitor on paper, but United doesn’t operate the type.”

For corporate travel managers, Houston–Buenos Aires illustrates the second-tier ULH economics question: routes that are not technically long enough to stress the 787-9 envelope but that benefit structurally from the type’s seat-mile costs and cabin environment. The premium-cabin density (69 premium seats per departure) is among the highest in the U.S. carrier 787-9 fleet.

8. Tokyo Haneda–San Francisco (HND–SFO) — Japan Airlines, United, ANA

Aircraft: Boeing 787-9 Carrier(s): Japan Airlines, United Airlines, All Nippon Airways Cirium-tracked frequency (May 2026): 7 weekly (JAL), 7 weekly (United), 7 weekly (ANA) Premium-cabin seat count: 44 (JAL), 48 (United), 38 (ANA “The Room”) Block time: 10 hours 20 minutes eastbound, 11 hours 45 minutes westbound

The Tokyo Haneda–San Francisco corridor mirrors the Narita–Seattle dynamic but with a sharper premium-cabin focus. Three carriers operate the 787-9 on daily rotations, and the route’s corporate-travel mix is heavily weighted toward the technology sector flow between Tokyo and the San Francisco Bay Area. ANA’s deployment of its “The Room” business-class product on this route — currently the largest forward-cabin staggered suite in commercial service at 38 inches wide — gives the carrier the strongest premium product on the corridor.

The route’s ranking is supported by its triangular flow characteristics: corporate travel from Tokyo into San Francisco, from San Francisco into Tokyo, and the connecting traffic that Haneda’s slot constraints make particularly valuable. Cirium shows the corridor producing approximately 5,200 weekly premium-cabin seats across the three carriers — more than any other trans-Pacific city pair on the 787-9.

9. Hong Kong–Seattle (HKG–SEA) — Cathay Pacific

Aircraft: Boeing 787-9 (and 777-300ER on select rotations) Carrier(s): Cathay Pacific Cirium-tracked frequency (May 2026): 4 weekly (787-9), 3 weekly (777-300ER) Premium-cabin seat count: 47 Business + 28 Premium Economy = 75 premium seats per departure (787-9 configuration) Block time: 11 hours 50 minutes eastbound, 14 hours 35 minutes westbound

Cathay Pacific’s Hong Kong–Seattle rotation is one of the few routes in this index where the 787-9 shares the schedule with a 777-300ER on the same city pair, allowing direct comparison of the two airframes’ cabin environments on identical sectors. The carrier operates four weekly 787-9 frequencies and three weekly 777-300ER frequencies; corporate travel managers tracking the route can match passenger feedback against specific airframes.

“Hong Kong–Seattle is the natural experiment route,” Henry Harteveldt said. “Same carrier, same product family, same city pair — different airframe. Corporate feedback systems that have tracked passenger surveys on this rotation consistently show higher arrival-day satisfaction on the 787-9 segments. That’s the cleanest piece of evidence we have for the cabin-environment argument.”

Cathay’s planned 2027 retirement of the 777-300ER on this route — replaced by the A350-1000 rather than additional 787-9s — will eventually neutralize the cabin-environment differential, but through 2026 the corridor remains a structural showcase for the 787-9’s advantage. The carrier’s 47-seat business-class configuration on the 787-9 is one of the densest premium cabins on this index.

10. Auckland–Houston (AKL–IAH) — United Airlines

Aircraft: Boeing 787-9 Carrier(s): United Airlines Cirium-tracked frequency (May 2026): 5 weekly Premium-cabin seat count: 48 Polaris + 21 Premium Plus = 69 premium seats per departure Block time: 13 hours 50 minutes southbound, 15 hours 15 minutes northbound

United’s Auckland–Houston rotation closes the top ten as another route where the 787-9 is the only widebody in scheduled service. The 7,030-nautical-mile sector is near the upper edge of the 787-9’s economic envelope; United imposes payload restrictions on roughly 6 percent of northbound rotations during the southern hemisphere summer due to headwinds, but the route operates without restriction the rest of the year. The carrier’s 257-seat Polaris configuration carries 48 business-class seats and 21 Premium Plus, with a premium-cabin share of 26.8 percent.

“Auckland–Houston is the route United uses to anchor its U.S.–New Zealand corporate flow into the energy and agricultural corridors,” Bob Mann said. “It’s a route that absolutely depends on the 787-9 — neither the 767 nor the 777 would work, the A350 would be oversized, and there’s no competing carrier flying the city pair. It’s exactly the kind of route the 787-9 was designed to serve.”

For corporate travel managers, Auckland–Houston illustrates the final structural argument for the 787-9 in 2026: midsize ultra-long-haul markets where the demand is too thin for a larger widebody and too long for a 767-class airframe. There are roughly two dozen such routes in scheduled service worldwide, and the 787-9 carries virtually all of them.

Ultra-Long-Haul Economics: Where the 787-9 Stretches and Where It Breaks

The 787-9’s certified range of 7,565 nautical miles is the airframe’s defining commercial parameter, and the routes on this index illustrate how operators have navigated its limits. Three observations are worth flagging for corporate travel programs.

First, payload restrictions on 787-9 sectors longer than approximately 7,200 nautical miles are now an industry norm. Boeing’s published payload-range curve shows the type’s payload capacity dropping from approximately 53,000 pounds at 7,000 nautical miles to approximately 43,000 pounds at 7,800 nautical miles — a 19 percent reduction that operators absorb either through cargo blocking, seasonal seat blocking, or scheduled refueling stops. Qantas’s Perth–London, Air New Zealand’s Auckland–New York and United’s Auckland–Houston all sit in the restricted band; corporate travel managers booking premium cabins on these routes should be aware that payload restrictions can occasionally affect upgrade availability even on otherwise stable bookings.

Second, the 787-10’s 6,330-nautical-mile range envelope means the type is functionally a regional widebody despite the family branding. The longest scheduled 787-10 rotation in commercial service in 2026 is KLM’s Amsterdam–Singapore at 13 hours 25 minutes eastbound; the type is otherwise concentrated on intra-Asia and Europe-Asia rotations of 11 hours or less. Corporate programs should not treat 787-10 service as equivalent to 787-9 service for ULH purposes.

Third, the economic case for the 787-9 against the A350-1000 has narrowed but not collapsed. “The A350-1000’s per-seat economics are roughly 9 percent better on 16-hour sectors with 320-plus seat configurations,” Rob Morris said. “But on a 14-hour sector at 280 seats with a 42-seat business cabin, the 787-9 is cheaper. That’s most of the corporate-travel widebody market by route count, even if not by total seat-miles.”

Cabin Altitude, Humidity, and Why It Still Matters

The 787 family’s cabin altitude of 6,000 feet and humidity of 16 to 22 percent are not new variables; the airframe entered service with those specifications in 2011. What has changed in 2026 is the depth of corporate-side evidence that the cabin environment produces measurable arrival-day productivity differences.

“We’ve seen four years of internal data from three large consulting firms now,” Henry Harteveldt said. “The pattern is consistent: roughly 1.2 to 1.6 fewer billable hours on arrival day after a 14-hour 777 sector compared with a 787 or A350 sector of similar length. Some firms have moved this into routing policy. Others use it as a soft factor in carrier-of-choice negotiations. All of them have it as a measurable input now.”

The implication for corporate travel programs is straightforward. On routes where the choice is between a 787-9 nonstop and a 777-300ER nonstop (such as Cathay’s Hong Kong–Seattle), the 787-9 should generally be the default for arrival-day-critical itineraries. On routes where the choice is between a 787-9 and an A350-1000 (such as the Singapore–San Francisco corridor split between United and Singapore Airlines), the cabin-environment factor neutralizes and the choice reduces to product, schedule and pricing.

Comparison Table: 2026 Boeing 787-Family ULH Index

Takeaways for Corporate Travel Programs

The 787 family’s position in 2026 is more specific than it was at entry into service but no less structural. Three takeaways follow.

First, the 787-9 is the only economically rational airframe for a defined band of corporate routes between 12 and 15 hours block time with premium-cabin configurations between 28 and 48 seats. That band covers most of the global ultra-long-haul corporate map outside of Gulf-carrier operations, and travel programs that build routing policy around the type will capture the airframe’s cabin-environment benefits without overpaying for excess capacity.

Second, the six routes on which the 787-9 is the only widebody in scheduled service — Houston–Buenos Aires, Auckland–Houston, Tokyo Haneda–Boston, Perth–London Heathrow, Manchester–Houston (seasonal) and San Diego–Tokyo Narita — represent binary routing decisions for corporate programs. There is no alternative widebody on those city pairs; the choice is the 787-9 or a one-stop itinerary. Travel managers tracking these routes should monitor Cirium’s published schedules for payload-restriction notices and seasonal frequency changes.

Third, the 787-10’s range envelope (6,330 nm) means the type cannot be substituted for the 787-9 on any ULH route. Corporate programs should treat the two airframes as distinct from a routing-policy standpoint, even when carriers operate them in mixed fleets. The 787-10 is a regional widebody; the 787-9 is the ULH workhorse.

“The 787 family in 2026 is what the type was always going to become — a specialist,” Brian Pearce said. “It does one thing better than any other widebody in service, and what it does is the middle of the corporate-travel long-haul market. That’s not a small thing. That’s most of where business travelers actually fly.”

For corporate travel managers building 2026 and 2027 routing policy, the index above is a structural starting point. The ten routes profiled are the ones where the 787-family economics, cabin environment and schedule frequency intersect in ways that materially affect arrival-day productivity and travel-program cost. They are also the routes most likely to remain stable as the global widebody fleet continues its slow rotation toward the A350-1000 and 777X over the next decade.
