Delta tipped to debut A350-1000 on Atlanta and Detroit to Seoul

Delta Air Lines is rumoured to be planning to introduce its new Airbus A350-1000 on nonstop services from Atlanta (ATL) and Detroit (DTW) to Seoul Incheon (ICN), according to Simple Flying. The report, published on 10 October 2026, stresses that the plan is unconfirmed and that the schedule has not been announced. The first aircraft is expected in early 2027.

What is being reported

Simple Flying says aviation commentator JonNYC suggested on X that the aircraft would begin flying from two of Delta Air Lines' busiest bases to Incheon. The outlet approached Delta for comment, but a spokesperson could not immediately be reached. No dates, frequencies or launch timings have been given.

The aircraft and Delta's plans

According to Simple Flying, Delta has a firm order for 20 A350-1000s, with options for 20 more. Deliveries are due to start with the first aircraft in early 2027. The report says it will be the largest type in Delta's fleet since the Boeing 747 was retired in 2017.

The jets are to use Rolls-Royce Trent XWB-97 engines and fly on flagship long-haul routes. Simple Flying says they will carry the next-generation Delta One seat, with the largest seat-back screens the airline has installed, and Delta One Suites with sliding privacy doors. The outlet states that up to half of each aircraft is dedicated to premium passengers.

Simple Flying says the type will replace older Boeing 767-300ERs, bringing more seats and fuel burn cut by up to 25%. It also cites a range of up to 9,100 nautical miles (16,850 km). It suggests Singapore could be added as early as next year, though that is also speculation.

Why Seoul

The outlet describes Seoul as Delta's largest international hub in Asia and a key gateway for connections around the Asia-Pacific region. Delta has a joint venture with Korean Air, which Simple Flying says carries about 2,000 daily passengers on either airline between the Americas and Asia, linking more than 290 destinations in the Americas and 80 in Asia. Both airlines use Terminal 2 at Incheon, which the report says eases connections, baggage transfers and lounge access. Most Delta hubs already have nonstop Seoul flights.

What this means for travellers

• Nothing is confirmed. No A350-1000 flights can be booked on these routes yet, and the rumour may change.
• If it proceeds, passengers between Atlanta or Detroit and Seoul could get the new Delta One Suites and the airline's newest long-haul cabin.
• Connections should stay straightforward for those continuing onward in Asia, as Delta and Korean Air share Terminal 2.
• Delta's timetable and aircraft assignments would be the place to check once the airline confirms details.

It is not yet known when the flights would start, how often they would run, or whether delivery timing could affect plans.
