Delta is now the only US airline flying the Airbus A350, and it is betting the future of its international network on the type. While United and American leaned into Boeing 777s and 787s, Delta retired all 18 of its 777s and handed flagship duties entirely to the A350-900, with 20 larger A350-1000s on order plus 20 options.
The most striking move is on the Pacific. By spring 2026, all 17 of Delta's continental US-to-Asia/Oceania routes will fly exclusively on the A350-900. Deep ocean sectors like Atlanta to Seoul Incheon and Detroit to Tokyo Haneda benefit from the jet's range of up to 8,100 nautical miles, while the displaced A330-900neos shift to transatlantic flying, where they are a better fit. A big part of the Pacific logic is Delta's joint venture with Korean Air: feeding premium travellers through Seoul across Asia is one of the airline's highest-yield businesses, and the A350 cabins are built for it, with 40 enclosed Delta One Suites and 40 Premium Select seats.
The A350-1000, targeted for entry into service in mid-2027, is an upgauging play. At slot-constrained airports like London Heathrow and Tokyo Haneda, adding frequencies is often impossible, so a bigger jet with 8,700 nautical miles of range is how Delta grows seats and cargo on dense routes. It also kicks off a neat fleet cascade: -1000s take over trunk routes from Atlanta, Detroit and Los Angeles, pushing -900s down to replace ageing 767s on transatlantic routes out of New York JFK and Boston, with A330neos backfilling further. Both variants share a single pilot type rating and maintenance setup, and Delta's 130,000-square-foot Atlanta engine shop handles Rolls-Royce Trent XWB overhauls in-house, trimming costs and even earning revenue servicing other airlines' engines.
For travellers, the real story is premium cabins. Some ultra-long-haul routes, including Atlanta to Johannesburg and Cape Town, get a denser premium A350 layout with 40 Delta One suites instead of 32, sacrificing 30 economy seats to boost revenue per flight. The A350-1000 will debut the next-generation Delta One suite: full-height sliding doors, memory foam cushions, 24-inch 4K QLED screens, Bluetooth audio, USB-C and universal AC power, all supported by expanded Delta One lounges at gateways like Los Angeles. In short, if you fly Delta long-haul in the coming years, expect more A350s, more suite inventory and a consistent premium product whether you are crossing the Pacific or heading to Southern Africa.
