Delta, American, United add 14 routes

Delta Air Lines, American Airlines and United Airlines have spent the past year filling out their summer 2026 international schedules with new long-haul routes, betting that demand for overseas leisure and premium travel will stay strong into next year. Across company announcements reviewed this week, Delta has outlined seven new Europe routes for summer 2026, American has announced six new international routes for the season, and United this week added two Japan flights for winter 2026-27. The combined push gives the three largest U.S. network carriers a broader map across Europe, South America and Asia as they head into the peak summer booking period. The announcements were made separately, not in a joint statement. ### Which routes has Delta added for summer 2026? Delta said its summer 2026 transatlantic buildout includes seven new Europe routes, part of what the airline described as its biggest transatlantic schedule yet. The airline’s route roundup published in November listed Boston-Madrid starting May 6, Seattle-Rome starting May 6, Seattle-Barcelona starting May 7, Boston-Nice starting May 16, New York-JFK-Olbia in Sardinia starting May 20, New York-JFK-Porto starting May 21 and New York-JFK-Malta starting May 22. (news.delta.com) Seattle is a key part of that expansion. Delta said in June 2025 that it would launch Seattle-Barcelona and Seattle-Rome in summer 2026, and President Glen Hauenstein said at the time the carrier was investing in new international service and premium facilities at Seattle-Tacoma International Airport. Paul Baldoni, Delta’s senior vice president of network planning, later said the additions to Porto, Malta and Sardinia would expand choice for customers and strengthen New York-JFK’s role as a global gateway.

American said on Aug. 7, 2025, that it would add six international routes for summer 2026, centered on Europe and one South America extension. The carrier said it would debut service to Prague and the only nonstop U.S.-Budapest flight, while also adding new routes to Athens, Milan and Zurich and extending Dallas Fort Worth-Buenos Aires deeper into the summer. (news.delta.com) Dallas Fort Worth is the anchor for much of that growth. American said Dallas Fort Worth-Athens and Dallas Fort Worth-Zurich would start May 21, 2026, and that the Buenos Aires extension would run from May 21 to Aug. 3, 2026. The same announcement said Philadelphia-Milan and Philadelphia-Budapest would start May 22, and Chicago-Prague would start May 23. Brian Znotins, American’s senior vice president of network and schedule planning, said customers were continuing to tell the airline that Europe was where they wanted to go each summer.

United said on May 14 that it would expand Japan service with a new daily year-round Chicago-Tokyo Narita flight beginning in October and a three-times-weekly seasonal San Francisco-Sapporo flight running from Dec. 11 through March 26. The carrier said the Sapporo route would be the first nonstop service from the continental United States to Sapporo and that it would be the only U.S. airline flying nonstop between Chicago and Tokyo Narita. (news.aa.com) Patrick Quayle, United’s senior vice president of network planning and global alliances, said the new flights were aimed at travelers headed to Japan for skiing, business trips and onward connections across Asia. United said it flew more than 1.8 million passengers between the United States and Japan in 2025, more than all other U.S. carriers combined, and that it expects to operate up to 13 daily flights from the continental United States to four Japanese airports this winter.

The route count reaches 15 if Delta’s seven summer 2026 Europe routes, American’s six summer 2026 international additions and United’s two newly announced Japan routes are counted together. The “14 routes” figure cited in some travel trade coverage appears to exclude one of those additions or to combine separate announcements on a different basis. Reuters could not independently verify a single Friday announcement by all three airlines covering 14 routes. (united.mediaroom.com) United also plans to resume Saipan-Tokyo Narita service on July 12, according to schedule-tracking reports and route filings published this month after a suspension tied to Typhoon Sinlaku. That resumption appears separate from United’s May 14 Japan expansion announcement. ### How busy is the broader summer shaping up to be? American said on May 10 that it expects to carry 75 million customers across 750,000 flights between May 21 and Sept. 8, which it described as its largest summer schedule to date. (news.delta.com) The airline said Memorial Day weekend alone is expected to bring more than 4.2 million customers across more than 40,000 flights. The next milestones are now set by launch dates already published by the carriers. (aeroroutes.com) Delta’s first summer 2026 additions begin May 6 with Boston-Madrid and Seattle-Rome, American’s first new seasonal service begins May 21 from Dallas Fort Worth to Athens and Zurich, and United’s new Chicago-Tokyo Narita service begins in October before San Francisco-Sapporo starts on Dec. 11.
