Delta Air Lines will introduce a new cabin design in fall 2024, initially used in a Boeing 757 on domestic flights and international short-haul routes. From early 2025, the new design will also be used in an Airbus A350. At the heart of the changes are new seat materials, an improved lighting concept and a modernized color palette designed to make the travel experience more pleasant. The design was specifically developed to offer passengers a comfortable and relaxing atmosphere on board. Delta placed particular emphasis on lighting, which is tailored to different phases of the flight to promote relaxation or productivity. Warm tones during boarding and atmospheric lighting during meal times are intended to set inviting accents. For sleep, blue tones are gradually reduced and replaced with warm amber tones to remind you of a sunset. These details are intended to help passengers better adapt to the respective time zone and make their journey more pleasant. In addition to the lighting, the choice of colors and materials in the cabin have also been revised. Delta is using natural materials and a modernized color palette that combines elegance and functionality. Brand-specific design elements have also been introduced to increase recognition. The aircraft's washrooms will also be modernized as part of this redesign.
