Longest Narrowbody Flights for Summer 2025
Airlines are pushing the boundaries of narrowbody performance this summer, as a record 57 routes featuring single-aisle aircraft now fly more than 3,000 nautical miles. Global travel data from OAG shows that the summer 2025 schedule will include 10 of the longest narrowbody flights, with aircraft like the Airbus A321LR, A321XLR, Boeing 737 MAX, and even the classic Boeing 757 powering these ultra-long-haul journeys.
Leading the pack is French all-business class carrier La Compagnie. Its Newark–Milan service covers an impressive 3,473 nautical miles and operates with an A321LR. This route, designated Flight B0301, boasts a block time of 7 hours 55 minutes and is scheduled 332 times during the summer season. La Compagnie also operates the second-longest narrowbody flight, the Newark–Nice route, which covers 3,471 nautical miles with a block time of 7 hours 45 minutes on Flight B0201. These flights are operated in an all-business class configuration, with fully lie-flat seats and 15.7-inch seatback touchscreens, making them a hit with discerning travelers.
Air Transat ranks third with its Lima–Montreal service on Flight TS151. Covering 3,404 nautical miles, this A321LR route takes about 8 hours 20 minutes and is scheduled 120 times over the summer. Catering primarily to leisure markets, Air Transat’s long narrowbody routes underline its commitment to connecting Latin America with Canada. The airline is also planning to launch additional long-haul services, including a return to Germany, which may challenge the current record holders.
United Airlines adds to the list with its Stockholm–Newark service on Flight UA69. This iconic route, flown on a Boeing 757, spans 3,404 nautical miles with an 8-hour 40-minute block time and is scheduled 176 times. Despite the 757’s gradual phase-out in favor of the incoming A321XLR, United continues to operate this venerable aircraft on one of its longest narrowbody routes.
Scandinavian carrier SAS has repurposed capacity from its discontinued Stockholm–Toronto flight to launch a new Copenhagen–Toronto service. Operating an A321LR on 414 flights during the summer, this route covers 3,383 nautical miles with a block time of 8 hours 40 minutes. The new service is part of SAS’s strategy to expand its SkyTeam network and optimize its narrowbody fleet.
Aer Lingus makes its debut with a Nashville–Dublin route on its new A321XLR. Covering 3,383 nautical miles in just 8 hours 5 minutes on Flight EI76, this service, scheduled 226 times, marks Dublin’s first direct link to Music City. Meanwhile, Iberia introduces its Washington–Madrid route on an A321XLR (Flight IB362), covering 3,306 nautical miles in 7 hours 50 minutes across 342 flights.
Other notable entries include Air Transat’s second service from Lima to Toronto (3,344 NM) and GOL Linhas Aéreas’ Brasilia–Orlando route (3,289 NM) operated on a Boeing 737 MAX. Together, these ultra-long narrowbody flights highlight a major shift in airline strategy, as carriers optimize efficiency and meet growing global demand for long-range, single-aisle travel. With summer 2025 set to be a record-breaking season, passengers can look forward to faster, more comfortable narrowbody journeys across continents.
