MIA-GRU leads the 2026 US-South America premium-cabin index at roughly 4,100 weekly business and first class seats across American and LATAM widebody operations, followed by JFK-GIG and IAH-SCL. Cirium schedules data shows total US-South America premium capacity running approximately 9 percent above the Q2 2019 baseline, with the bulk of post-pandemic growth concentrated on Miami and Houston flows tied to commodities, mining, agribusiness, and Brazilian wealth-management activity. Henry Harteveldt of Atmosphere Research has described the corridor as 'the most procurement-complicated long-haul Americas market a corporate program has to manage in 2026, because no single alliance owns it cleanly.' The LATAM-Delta joint venture restructure, finalized in October 2022, and the partial LATAM-American codeshare restoration that began in 2024 have produced an alliance map that does not resemble the pre-2020 status quo.
The US-South America premium business-travel network is the most procurement-complicated long-haul corridor in the Americas in 2026. Cirium schedules data for the second quarter of 2026 shows total scheduled premium-cabin capacity between US gateways and South American destinations at approximately 31,000 weekly seats, running about 9 percent above the Q2 2019 baseline. The headline number understates the structural reorganization. The 2020 LATAM exit from oneworld, the LATAM Chapter 11 process and its 2022 emergence, the formation and 2022 finalization of the LATAM-Delta joint venture, the 2024 partial American-LATAM codeshare restoration, and the 2025 JetBlue JFK-GIG relaunch have collectively produced an alliance map that bears almost no resemblance to the pre-pandemic configuration.
Three structural factors shape the corridor in 2026. The first is commodities-sector demand. Houston, Dallas-Fort Worth, and to a lesser degree Miami serve as the US-side anchors for corporate travel into the Andean mining belt (Chile, Peru), the Argentine and Brazilian agricultural complex, the Colombian oil-and-gas and coffee sectors, and the Brazilian iron-ore, soybean, and sugar export complex. Atmosphere Research’s 2026 Latin America corridor brief characterizes the post-pandemic recovery on these flows as “commodities-cycle correlated rather than nearshoring-correlated, which is the opposite of the US-Mexico story and explains why the South American premium-cabin recovery has been more uneven than the Mexico recovery.” The second is Miami’s role as the de facto private-banking and wealth-management hub for Brazilian and Argentine high-net-worth flows, which sustains a structurally elevated MIA-GRU and MIA-EZE premium-cabin demand profile that does not move with the commodities cycle in the same way. The third is the alliance reorganization itself, which has redistributed corporate procurement leverage in ways that reward carriers with widebody gauge and disadvantage carriers without it.
This analysis ranks ten US-South America routes by their Q2 2026 premium-cabin seat capacity, frequency consistency, corporate-traveler intent density, and widebody product quality. Routes are evaluated on operating-carrier metal only; codeshare seats are excluded from the capacity counts.
What the Cirium capacity data shows
Cirium’s Diio Mi schedule database, reconciled against US DOT T-100 segment filings and OAG Schedules Analyser, shows approximately 31,000 weekly scheduled premium-cabin seats between US gateways and South American destinations in the second quarter of 2026. That compares with approximately 28,500 in Q2 2019 and approximately 26,000 in Q2 2024. Recovery has been uneven by endpoint. Brazil (GRU and GIG combined) accounts for approximately 38 percent of total US-South America premium-cabin capacity in 2026, up from roughly 35 percent in 2019. Chile (SCL) has grown to approximately 14 percent on the back of mining-sector and lithium-corridor expansion, up from 12 percent in 2019. Argentina (EZE) has recovered to roughly 16 percent after running below 11 percent during the 2021-2022 inflation-driven demand collapse. Peru (LIM) and Colombia (BOG) have grown more modestly, with LIM at approximately 13 percent and BOG at approximately 9 percent of total premium capacity.
Miami remains the dominant US-side gateway, handling approximately 51 percent of total US-South America premium-cabin capacity in 2026 — a share that has compressed from 56 percent in 2019 as Atlanta, JFK, and Houston have absorbed share through the LATAM-Delta JV build-out and selective Andean route expansion. New York-JFK has grown to approximately 15 percent on the back of the JetBlue JFK-GIG relaunch and continued American and LATAM service into EZE and GIG. Houston Intercontinental sits at approximately 13 percent, anchored by the IAH-SCL rotation and the energy-sector flows that have made it the secondary commodities gateway. Atlanta has grown to roughly 11 percent following the LATAM-Delta JV restructure and Delta’s A350-900 redeployment onto ATL-GRU.
Equipment composition across the network is overwhelmingly widebody. Cirium fleet data shows that approximately 96 percent of Q2 2026 US-South America premium-cabin seats are operated on widebody equipment, with the 787-8 and 787-9 the dominant frames across American, LATAM, and United, the A350-900 carrying Delta’s ATL-GRU and JFK-GIG operations, the 777-300ER on selected American rotations into GRU and EZE, and the A330-200 and A330-300 across LATAM’s intra-network deployments. The narrowbody exception is JetBlue’s A321LR operation on JFK-GIG, which delivers Mint Studios at the long edge of the aircraft’s design envelope and represents the most consequential narrowbody premium long-haul experiment in the Latin American market.
OAG’s 2026 Latin America premium connectivity brief frames the procurement implication: the US-South America network is the canonical case where alliance fragmentation has outpaced the ability of any single corporate program to source the corridor through a single preferred carrier. The 2024 American-LATAM partial codeshare restoration narrowed but did not eliminate the gap that opened in 2020. The LATAM-Delta JV has produced metal-neutral selling on roughly three-quarters of eligible city pairs but does not cover Miami, where LATAM’s largest US gateway sits. Bob Mann has summarized the procurement reality as “a corridor where the dominant city-pair leadership rotates by endpoint — American owns Miami, Delta owns Atlanta through the LATAM JV, United owns Houston, and JFK is genuinely contested by three carriers in three different alliance configurations.”
Methodology
Each of the ten routes was scored against four weighted criteria.
Cirium-tracked weekly premium-cabin seat capacity (40 percent) — The sum of business and first class scheduled seats per direction per week in the second quarter of 2026, summed across all carriers operating the route nonstop. American Flagship Business, Delta One Suites, United Polaris, LATAM Premium Business, JetBlue Mint Studios, Avianca Business, and Aerolíneas Argentinas Business Club are all counted as premium-cabin equivalents. Code-shared seats are excluded; only operating-carrier metal counts toward the capacity total.
Frequency consistency (20 percent) — Daily or multi-daily year-round service across all operating carriers earns full credit. Sub-daily, seasonal, or operationally inconsistent rotations earn partial credit. Cirium’s twelve-month forward schedule was used to identify routes with announced 2026 changes, including the IAH-EZE seasonal pattern and the JetBlue JFK-GIG full-year ramp.
Corporate-traveler intent density (25 percent) — A composite of US DOT T-100 origin-destination data, IATA AirportIS premium-cabin yield data, and documented sector exposure at the South American endpoint. Commodities, mining, oil and gas, agribusiness, banking, and wealth-management corridors receive intent-density credit proportional to documented corporate-travel volume. Tourism-anchored gateways without corporate-meeting overlay are credited at a reduced coefficient.
Widebody product quality (15 percent) — Routes operated predominantly on 787, A350, A330, or 777 metal with lie-flat business-class seating earn full credit. The JetBlue A321LR Mint Studios operation is treated as a special case, credited at a full coefficient on product quality but with a flag on aircraft gauge in the qualitative discussion.
The ranked routes
1. MIA-GRU (Miami-São Paulo Guarulhos) — American, LATAM
Miami-Guarulhos is the single most important US-South America premium business route, carrying approximately 4,100 weekly premium-cabin seats in Q2 2026 across American and LATAM widebody operations. American operates the rotation with three-times-daily 777-300ER and 787-9 service; LATAM operates twice-daily 787-9 and selected 777-300ER rotations. The route is the principal channel for Brazilian wealth-management flows into Miami’s private-banking corridor, for US-Brazil M&A activity, and for the commodities-trading and agribusiness corporate-travel volumes that anchor São Paulo’s role as the financial capital of the Southern Cone. The 2024 American-LATAM codeshare restoration covers the route, restoring frequent-flyer earning and lounge reciprocity that had been absent since 2020.
Cirium yield data shows MIA-GRU consistently ranking in the top five US international routes by premium-cabin revenue per available seat mile, a reflection of the structurally elevated wealth-management demand profile and the absence of a metal-neutral JV that would normally compress yield through coordinated capacity. Henry Harteveldt has described MIA-GRU as “the route that proves long-haul premium-cabin pricing can sustain at a level uncorrelated with the commodities cycle when wealth-management and financial-services demand carries the structural floor.”
2. JFK-GIG (New York-Rio de Janeiro Galeão) — American, LATAM, JetBlue
JFK-Galeão has been transformed by the JetBlue relaunch. Cirium weekly capacity tracking puts the route at approximately 3,200 weekly premium-cabin seats in Q2 2026, up from roughly 2,600 in Q2 2024 before JetBlue resumed service. American operates daily 777-200ER service; LATAM operates daily 787-9 service; JetBlue operates daily A321LR Mint Studios service. The carriers represent three distinct alliance configurations — American with the partial LATAM codeshare, LATAM through the Delta JV (though Delta does not operate JFK-GIG directly), and JetBlue as an unaligned operator with its own American Airlines partnership framework.
The corporate-traveler profile on JFK-GIG is dominated by US-Brazil energy-sector activity, particularly the offshore pre-salt oil and gas complex anchored in Rio de Janeiro and Macaé, and by US banking and asset-management coverage of Brazilian capital-markets flows. The JetBlue Mint Studios product on the A321LR represents the most aggressive narrowbody premium long-haul experiment in the Latin American market. Industry analysts have flagged the route as a leading indicator for whether the A321LR and A321XLR can sustain corporate-cabin demand on flights of nine-plus hours.
3. IAH-SCL (Houston-Santiago) — United, LATAM
Houston-Santiago is the dominant US-Chile premium business route and the canonical commodities-corridor flight in the Americas, carrying approximately 2,800 weekly premium-cabin seats in Q2 2026. United operates daily 787-9 service; LATAM operates daily 787-9 and selected 777-300ER service. The route serves the Chilean copper-mining belt (Escondida, Collahuasi, Codelco’s Chuquicamata and El Teniente operations), the lithium-extraction complex in the Atacama, and the Houston-headquartered energy-services majors that maintain Andean coverage from Texas.
The LATAM-Delta JV covers the route from the LATAM side, but United is the dominant US-side carrier and is not part of the JV. The result is a route where corporate procurement programs typically split allocation between United Polaris (for direct Star Alliance routing through Houston) and LATAM Premium Business (for connectivity into the broader LATAM South American network from Santiago). Bob Mann has noted that IAH-SCL “is the route where the limits of the LATAM-Delta JV become most visible — Delta has no Houston widebody operation to plug into the corridor, so the JV cannot compete with United on the most procurement-relevant US gateway for the Chilean copper sector.”
4. MIA-LIM (Miami-Lima) — American, LATAM
Miami-Lima carries approximately 2,600 weekly premium-cabin seats in Q2 2026 across American and LATAM widebody operations. American operates twice-daily 787-8 and selected 787-9 service; LATAM operates twice-daily 787-9 service with the carrier’s Premium Business product. The route is anchored in Peruvian mining-sector corporate travel — copper, gold, zinc, and silver — and in the broader Andean banking and capital-markets coverage that Lima has consolidated since the 2020s.
The 2024 American-LATAM partial codeshare covers MIA-LIM, restoring the bilateral frequent-flyer and lounge reciprocity that had been absent during the 2020-2024 unwind period. Lima’s Jorge Chávez International Airport completed its expanded terminal in 2025, easing the chronic widebody-gate constraints that had bottlenecked the route through the early 2020s. Cirium yield data shows MIA-LIM premium-cabin revenue per available seat mile running approximately 18 percent above the Latin American corridor average, reflecting the mining-sector demand profile and the relative absence of low-cost-carrier competition in the premium cabin.
5. MIA-EZE (Miami-Buenos Aires Ezeiza) — American, LATAM, Aerolíneas Argentinas
Miami-Buenos Aires carries approximately 2,400 weekly premium-cabin seats in Q2 2026 across three carriers. American operates daily 777-200ER service; LATAM operates daily 787-9 service; Aerolíneas Argentinas operates daily A330-200 service. The route is the principal US channel for Argentine wealth-management flows into Miami’s private-banking corridor, for US-Argentina agribusiness coverage (soybean, beef, wine, lithium), and for the corporate-services coverage that the post-2024 Argentine macroeconomic stabilization has revived.
The carrier mix is unusually fragmented. American and LATAM operate under the 2024 partial codeshare. Aerolíneas Argentinas operates outside any meaningful US alliance framework, with the SkyTeam membership that the carrier has maintained since 2012 providing limited commercial integration with Delta given Delta’s separate LATAM JV. Henry Harteveldt has described the MIA-EZE carrier mix as “the most genuinely tri-polar premium long-haul route in the Americas, where corporate programs cannot rely on any single alliance to capture the full city-pair offering.”
6. DFW-LIM (Dallas-Fort Worth-Lima) — American
Dallas-Lima carries approximately 2,100 weekly premium-cabin seats in Q2 2026, operated exclusively by American on twice-daily 787-9 service following the 2025 upgauge from 787-8 metal on most rotations. The route is the secondary US gateway for the Peruvian mining sector and the principal channel for the Texas-headquartered oilfield-services and engineering-procurement-construction firms that maintain Andean coverage from Dallas-Fort Worth.
American’s exclusive operation on the route reflects the post-2020 LATAM departure from oneworld and LATAM’s decision not to compete head-to-head with American on the secondary Andean gateways from Texas. The 2024 partial codeshare restoration covers DFW-LIM and provides LATAM-network connectivity for American customers, though LATAM does not operate metal on the route. Cirium yield data shows DFW-LIM running at premium-cabin yields comparable to MIA-LIM, a reflection of the corridor’s commodities-correlated demand profile and the limited intra-corridor competition.
7. ATL-GRU (Atlanta-São Paulo Guarulhos) — Delta, LATAM
Atlanta-Guarulhos has been transformed by the LATAM-Delta JV. The route carries approximately 1,900 weekly premium-cabin seats in Q2 2026, up from approximately 1,400 in Q2 2024 before Delta redeployed A350-900 metal in place of the previous 767-400ER configuration. Delta operates daily A350-900 service with Delta One Suites; LATAM operates daily 787-9 service. The route is the principal LATAM-Delta JV widebody operation into Brazil and the canonical illustration of how the post-2022 JV has rebuilt a coordinated capacity offering that did not exist during the 2020-2022 LATAM Chapter 11 process.
The corporate-traveler profile on ATL-GRU is dominated by US Southeast headquartered multinationals — Coca-Cola, Delta, Home Depot, UPS — with significant Brazilian operations, and by the Atlanta-headquartered logistics and consumer-goods firms that have built Brazilian distribution networks. Bob Mann has framed ATL-GRU as “the cleanest example of the LATAM-Delta JV functioning as designed — metal-neutral selling, coordinated capacity, A350 product on the Delta side, 787-9 product on the LATAM side, and a city pair where the procurement decision genuinely runs through the JV rather than around it.”
8. MIA-BOG (Miami-Bogotá) — American, Avianca
Miami-Bogotá carries approximately 1,700 weekly premium-cabin seats in Q2 2026 across American and Avianca widebody and narrowbody operations. American operates three-times-daily service on a mix of 787-8 and 757-200 metal; Avianca operates four-times-daily service on 787-8 and A330-300 metal. The route is the highest-frequency US-Colombia premium business operation and the principal channel for US-Colombia oil-and-gas, coffee, banking, and corporate-services coverage.
Avianca is the operationally dominant carrier on the route despite American’s three-times-daily service, reflecting Avianca’s Bogotá hub and the carrier’s broader US-Colombia network depth. The route is unusual in the US-South America corridor for its mixed widebody-narrowbody equipment composition on the American side, with the 757-200 carrying selected rotations alongside 787-8 metal. Cirium fleet planning notes have flagged the 757-200 deployment as transitional, with American expected to migrate the route to all-widebody operation as the 757 fleet retires through the late 2020s.
9. IAH-EZE (Houston-Buenos Aires Ezeiza) — United (seasonal)
Houston-Buenos Aires occupies an asterisked position in the 2026 ranking. United’s announced schedule includes daily 787-8 service on a seasonal Q4-Q1 pattern, but the route did not operate consistently through Q1 2026 and Cirium’s twelve-month forward schedule shows continued operational uncertainty. When operating, the route carries approximately 1,200 weekly premium-cabin seats. The corporate-traveler profile is dominated by Houston-headquartered energy-sector coverage of the Argentine Vaca Muerta shale complex and by the agribusiness-services firms that maintain Buenos Aires coverage from Texas.
The route’s seasonal-and-inconsistent pattern reflects both the post-2020 Argentine macroeconomic volatility that has compressed premium-cabin demand at certain points in the cycle, and the operational difficulty of sustaining a Houston-Buenos Aires rotation against the more capacity-rich Miami and New York gateways. United has signaled intent to restore consistent year-round operation as Argentine demand stabilizes through the post-2024 macroeconomic adjustment, but corporate procurement programs should treat IAH-EZE as a contingency rather than a primary routing for 2026 sourcing.
10. JFK-EZE (New York-Buenos Aires Ezeiza) — American, LATAM, Aerolíneas Argentinas
New York-Buenos Aires carries approximately 1,500 weekly premium-cabin seats in Q2 2026 across three carriers. American operates daily 777-200ER service; LATAM operates daily 787-9 service through the Delta JV connectivity; Aerolíneas Argentinas operates daily A330-200 service. The route is the secondary US gateway for Argentine wealth-management flows (after Miami) and the principal New York-side channel for US-Argentina banking, capital-markets, and corporate-services coverage.
The carrier mix mirrors MIA-EZE in its tri-polar alliance configuration but at lower frequency and capacity. JFK-EZE’s corporate-traveler profile skews more toward financial-services and asset-management coverage of Argentine sovereign and corporate debt issuance, where New York’s role as the principal underwriting and settlement venue for Argentine capital-markets activity sustains a structurally elevated New York-Buenos Aires premium-cabin demand floor. Cirium yield data shows JFK-EZE running at premium-cabin yields approximately 12 percent above the Latin American corridor average, reflecting both the financial-services demand profile and the absence of a metal-neutral JV that would compress yields through coordinated capacity.

Takeaways for corporate travel programs
Three procurement implications follow from the 2026 ranking.
First, the US-South America corridor cannot be sourced through a single preferred carrier in the way that the US-Mexico or transatlantic Europe corridors increasingly can. The alliance map is genuinely fragmented — American dominant in Miami, Delta dominant in Atlanta through the LATAM JV, United dominant in Houston, JFK genuinely contested by three carriers in three different alliance configurations, and Aerolíneas Argentinas operating outside any meaningful US alliance framework on EZE flows. Corporate procurement programs that attempt to consolidate the corridor into a single carrier relationship will systematically underperform on either coverage, price, or product quality. The 2024 American-LATAM partial codeshare restoration narrowed but did not close the procurement gap that opened in 2020.
Second, equipment gauge is a binding constraint on this corridor in a way that it is not on US-Mexico. Approximately 96 percent of premium-cabin capacity is operated on widebody metal, and the lie-flat business class product expectations that long-haul Latin sustains do not translate down to narrowbody equipment on most rotations. The JetBlue A321LR JFK-GIG experiment is the exception that proves the rule — it is being closely watched precisely because narrowbody long-haul premium has not yet been proven in the Latin American market. Travel managers should evaluate routes on cabin product and frequency rather than on aircraft gauge in the US-Mexico style, but the underlying gauge baseline is widebody.
Third, the commodities-cycle correlation is real and procurement-relevant. The Houston, Dallas-Fort Worth, and Andean-anchored routes (IAH-SCL, DFW-LIM, MIA-LIM, IAH-EZE when operating) move with the copper, lithium, oil, and agribusiness cycles in ways that the Miami and New York wealth-management-anchored routes do not. Corporate programs with significant commodities-sector exposure should expect premium-cabin demand and pricing on these routes to be more cyclical than the corresponding US domestic or transatlantic corridors, and should build hedging into multi-year procurement contracts accordingly.
The US-South America corridor in 2026 is a corridor that rewards procurement sophistication and punishes the assumption that the pre-2020 alliance map still applies. The carriers that have rebuilt commercial structures since the LATAM oneworld exit — the LATAM-Delta JV in particular, and the American-LATAM partial codeshare more narrowly — have done so against a Latin American macroeconomic and operational backdrop that remains more volatile than the US-Mexico equivalent. The ten routes ranked here will continue to define the corporate-travel topology of the Americas through the remainder of the decade.
Frequently Asked Questions
- How were the ten US-South America routes ranked?
- Routes were scored against four weighted criteria: Cirium-tracked weekly premium-cabin seat capacity in the second quarter of 2026 (40 percent), daily-versus-sub-daily frequency consistency across all operating carriers (20 percent), corporate-traveler intent density derived from US DOT T-100 origin-destination filings and sector exposure at the South American endpoint — commodities, mining, banking, agribusiness, oil and gas (25 percent), and equipment gauge plus widebody premium-cabin product quality (15 percent). Seasonal-only operations and routes that have been suspended for more than two consecutive quarters since 2022 were excluded from the primary ranking but flagged where they remain on Cirium's announced forward schedule.
- How has the LATAM-Delta joint venture changed the US-South America premium map?
- The LATAM-Delta joint venture, formed after LATAM exited the oneworld alliance in 2020 and finalized in its current form in October 2022 following the LATAM Chapter 11 emergence, is now the dominant commercial structure on Brazil, Peru, Colombia, and Ecuador flows from Atlanta, New York-JFK, and Los Angeles. Cirium revenue-management data shows metal-neutral selling and coordinated capacity planning across approximately 78 percent of LATAM-Delta JV-eligible US-South America city pairs in 2026. ATL-GRU, which had been a Delta-only operation, now sees coordinated capacity with LATAM's GRU-based widebody fleet. Bob Mann of R.W. Mann and Company has noted that the JV 'reorganized the procurement logic on the eastern Brazil and Andean routes more substantively than any other Americas alliance event since the Aeroméxico-Delta JV formation.'
- What is the status of the LATAM-American Airlines commercial relationship after the 2020 breakup?
- After LATAM exited oneworld in 2020 and unwound its long-running codeshare with American, the two carriers operated as direct competitors on Miami and Dallas-Fort Worth flows for roughly three years. In 2024, following the LATAM Chapter 11 emergence and the stabilization of the LATAM-Delta JV, American and LATAM filed for and received US Department of Transportation approval for a limited bilateral codeshare covering selected US-South America city pairs including MIA-GRU, MIA-LIM, MIA-EZE, and JFK-EZE. The codeshare is narrower than the pre-2020 arrangement and does not include revenue sharing or metal-neutral selling, but it does restore frequent-flyer earning and reciprocal lounge access on covered itineraries. Henry Harteveldt has framed the reconciliation as 'the American Airlines acknowledgment that the Miami-South America franchise is too important to manage without LATAM in some form.'
- Which routes have seen the most material 2025-2026 capacity changes?
- Three. First, JetBlue resumed JFK-GIG in late 2025 after a multi-year suspension, adding daily A321LR service with the carrier's Mint Studios product and a US DOT-filed open-skies frame; the relaunch lifted JFK-GIG total weekly premium capacity by roughly 24 percent. Second, ATL-GRU saw Delta deploy A350-900 metal on the rotation in early 2026 in place of the previous 767-400ER, increasing Delta One Suites seat count per departure by approximately 35 percent. Third, American's DFW-LIM has been upgauged to 787-9 from 787-8 on most rotations, reflecting Peruvian mining-sector and commodities-export traffic recovery. IAH-EZE has remained on United's announced seasonal schedule but did not operate consistently through Q1 2026, and is included in the ranking with that caveat.
- Should a corporate program standardize on widebody routings into South America?
- Yes, with one exception. Cirium fleet data shows that approximately 96 percent of Q2 2026 US-South America premium-cabin seats are operated on widebody equipment — 787-8, 787-9, 777-200ER, 777-300ER, A330-200, A330-300, and A350-900 frames. Flight times of seven to eleven hours, overnight scheduling on most rotations, and the lie-flat business class product expectations of corporate travelers on long-haul Latin make widebody routings the default. The exception is JetBlue's A321LR JFK-GIG operation, which delivers a competitive Mint Studios product on narrowbody equipment over a flight time that sits at the long edge of what the 321LR is designed for. Travel managers should evaluate the JetBlue option on cabin product and frequency rather than dismissing it on aircraft type.
