Delta Air Lines is set to update the cabins of its Boeing 757 and Airbus A350 jets.The 757s being updated are at least 20 years old as Delta waits on delayed new 737 jets.New cabins feature memory foam cushions in economy plus a refreshed business class.

Delta Air Lines unveiled a new cabin design on Tuesday.

It’s set to debut on a Boeing 757, operating short-haul routes, later this fall. And early next year, Delta says, it will feature on longer international journeys with an Airbus A350.

Delta’s cabin refresh comes after an upcoming delivery of new jets was postponed. In its third-quarter earnings report released last Thursday, Delta said it expects its first Boeing 737 Max 10 to be delivered in 2026 — delayed from its original 2025 target.

The Max 10 is the largest version of Boeing’s newest narrowbody jet, but is yet to be certified amid a difficult period for the embattled planemaker.

Delta’s 757s are all at least 20 years old, and the airline has ordered 100 Max 10s that are likely to serve similar routes.

The new cabin design has been in the works for months, with plans first reported by The Points Guy in February.

It will feature a “warmer and more modern color palette” that includes a red accent stripe and the airline’s logo on seat tags, Delta said.

An enhanced mood lighting program should help passengers better adjust to a new time zone, Delta said. Flying economy on a widebody jet like the A350 will also come with memory foam cushions.

In Delta One, the airline’s business class, the fabric seats are made from a lighter material that should help regulate a passenger’s temperature.

The bathrooms are also set to be updated, with bright walls, a new floor, and an accent wall opposite the mirror.
