Delta transforms plane cabin interiors: See what's new inside the updated fleets

As airlines compete to keep passengers comfortable, Delta unveiled its newly redesigned interiors featuring fresh seat coverings, softer more modern color schemes, mood lighting and even memory-foam cushions.

This week, the Atlanta-based carrier released first look photos of the modern airplane refresh that will begin rolling out this fall and continue progressively across its full fleet over the next few years.

Passengers can expect a combination of new seating materials, enhanced lighting and an updated color palettes, plus new design elements with decorative motifs and signature branding.

"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," Mauricio Parise, Delta's VP of customer experience design, said in a statement.

Delta based its nose-to-tail transformation on "extensive feedback and research," which for the widebody jets will include memory-foam cushions.

The airline has reimagined its brand color palette to appear softer and more modern, swapping out the royal blue commonly seen on the plane seats today for a deeper midnight blue with red piping accents. The seat design also pulls in more natural materials with a wool blend for its updated fabrics.

Delta logos and seat tags will be used as subtle distinctions between cabins on all widebody aircrafts in Delta One and Delta Premium Select.

There will new be mood lighting suited to each phase of the flight to help customers feel "well-grounded and better adjusted to their time zone."

"We’ve focused on creating warm, calming and atmospheric lighting options that create an environment for customers to rest and relax, or stay productive as they wish," Parise said.

Warmer lights during boarding are meant to make the cabin "appear spacious and open," while mealtime will switch to "hues that feel like you’re at a candlelit dinner," he explained. For sleep, the cabin will bring in warm amber tones to evoke a natural sunset glow and once it’s time to wake up, will slowly brighten into a morning light.
