Delta Air Lines is giving its cabins a whole new look with a new color palette, breathable materials, memory foam cushions, and more.

The new design will debut later this fall on narrowbody Boeing 757 aircraft flying domestic and short haul international routes, followed by the airline’s Airbus A350 aircraft in early 2025, according to Delta. The refresh will include upgrades for every fare class from Delta One to Main Cabin.

“Delta has a 100-year history of creating a customer experience that feels welcoming and thoughtful with intentional design elements woven into every aspect of a customer’s travel,” Mauricio Parise, the vice president of customer experience design at Delta, said in a statement. “As we embark on our next century of flying, this refreshed cabin interior infuses utility with beauty to create an atmosphere that feels fresh, elevated, and timeless while reflecting our customers’ evolving tastes and expectations.”

Parise added the company was “intentional in creating an experience that mimics our customers’ lifestyles and puts them at ease as soon as they board our aircraft.”

In Delta One, the airline’s business class, travelers will sit on breathable fabric seats made of wool and nylon intended to help regulate passengers’ temperatures, and relax in their suites with engineered leather headrests.

Travelers in First Class and Premium Select, the airline’s premium economy, will notice new seat covers over memory foam cushions; while the carrier’s Comfort+ and Main Cabin seats will benefit from updated black seats with red accents in engineered leather. On Delta’s widebody aircraft, Comfort+ and Main Cabin seats will also include new memory foam cushions.

Delta will also upgrade the onboard lighting to use during different parts of the flight. When travelers board, they will be greeted with “warm and inviting lighting that makes the cabin appear spacious and open,” Parise said, followed by “hues that feel like you’re at a candlelit dinner” during mealtimes. The airline will slowly remove blue light when dimming the cabin lights to sleep and slowly brighten them again when it is time to wake up.

Lavatories will also get a makeover with bright walls, azure blue cabinets, and an accent wall.

Delta isn’t alone in overhauling its cabins. This summer, Finnair completed a $200 million refresh of its cabins, and Delta’s partner LATAM is adding a brand-new business class suite and ergonomically-designed economy seats to its fleet next year.
