Dallas/Fort Worth has reclaimed the title of American’s busiest long-haul airport from London Heathrow, with new Athens and Zurich routes powering a summer schedule shake-up.
Dallas/Fort Worth International Airport has overtaken London Heathrow as American Airlines’ top long-haul airport this summer, reversing a four-year run by the British airport as new European routes lift Texas departures.
American plans 2,073 outbound long-haul departures from DFW in the third quarter of 2026, compared with 1,932 from Heathrow, according to an analysis of Cirium Diio schedule data by the aviation outlet Simple Flying. The analysis defines long-haul as any nonstop flight of at least 2,650 nautical miles — a little more than 3,100 statute miles, or about 5,000 kilometers — and uses the third quarter, July through September, as its summer measuring period.
American’s DFW long-haul flying is up 6% from the same quarter last year, while its Heathrow long-haul operation has fallen 13% over the same period, the analysis found. DFW’s gain pushes its average outbound long-haul departures to 23 a day this summer, with daily totals ranging from 18 in late September to as many as 25 in early August, according to the Cirium Diio figures.
The shift reflects American’s deepening investment in DFW, which the airline calls its “largest and most connected hub,” with more than 230 nonstop destinations. American has rolled out a new 13-bank flight schedule meant to spread more than 930 peak daily departures more evenly through the day, and it is building a new $4 billion Terminal F at the airport under a Use and Lease Agreement extension through 2043.
“DFW is American’s largest and most critical hub, and with this expanded plan for Terminal F, DFW has a clear path to become the largest airline hub in the world,” American Airlines CEO Robert Isom said.
New Routes Fuel DFW’s Growth
DFW’s long-haul growth is tied to new international routes. The airport received its first-ever nonstop service to Athens on May 21, 2026, operating daily through early September with Boeing 777-200ER and 777-300ER aircraft. Zurich service resumed the same day after a 19-year absence, flying daily through Aug. 4 with the 777-200ER and 777-300ER.
“New service to Athens and Zurich is a great example of how American continues to invest in its largest hub with even more opportunities to connect to destinations around the world,” said Jim Moses, American’s senior vice president of DFW operations.
American also added summer service on its long-running DFW-Buenos Aires route, which had typically operated only in the Northern Hemisphere winter; the carrier is now flying up to four weekly flights on the route in July and August with Boeing 787-8 aircraft. Service to Honolulu, 3,288 nautical miles away, has grown from once daily to twice daily through early September with 787-8 and 787-9 aircraft.
“As the operating environment and our customers’ expectations have evolved in the last 10 years, our approach at our largest and most impactful hub must also evolve,” Moses said. “We’re making this significant shift while maintaining the same breadth, depth and schedule quality our customers expect and depend on. That means good things for American’s customers, our team members and just about everyone who depends on the airline.”
Why Heathrow Pulled Back
American’s pullback at Heathrow is not a retreat from London. It stems from scheduling adjustments tied to American’s transatlantic joint venture with British Airways, under which the two carriers operate on a metal-neutral basis.
This summer, American’s Heathrow schedule includes 21 daily departures to 10 U.S. cities: Boston, Charlotte, DFW, JFK, Los Angeles, Miami, Chicago O’Hare, Philadelphia, Phoenix and Raleigh-Durham. Compared with a year earlier, American cut Heathrow-DFW service from five daily flights to four, Heathrow-JFK from four daily to three, and Heathrow-Miami from two daily to one, changes tied to moves by British Airways.
British Airways resumed Heathrow-DFW service in October 2025 after not operating the route the previous summer. American had added a fifth daily DFW-Heathrow flight to cover the gap and trimmed it back once British Airways returned. British Airways also ended its London Gatwick-to-JFK route and shifted that capacity to Heathrow, raising its Heathrow-JFK schedule to nine daily flights, while doubling its Heathrow-Miami service to twice a day.
“We know that most of our customers prefer to fly from Heathrow when travelling to New York, which is where all nine of our daily JFK flights will depart from in Summer 2026,” a British Airways spokeswoman said.
A Pattern of Changing Leadership
The Heathrow-to-DFW swing fits a recurring pattern rather than a one-time event. American’s top long-haul airport has changed hands repeatedly over the past two decades: Chicago O’Hare led in the third quarter of 2006, Heathrow held the top spot from 2007 through 2010, JFK led in 2011, Heathrow returned in 2012, Miami was first from 2013 through 2015 when it handled far more South American long-haul flying than it does today, and DFW led from 2016 through 2021 before Heathrow reclaimed the position from 2022 through 2025, according to the Cirium Diio analysis.
DFW has been an American hub since 1981 and now connects to more than 230 destinations in 30 countries on peak days, the airline says.
