Bathrooms are also getting a refresh with bright walls and an accent wall opposite the mirror in Delta’s Celestial Sky pattern. Lavatory cabinets will be azure blue, and flooring will be a color-specked, smooth material for better cleanliness and traction.

The airline, which next year will celebrate it centennial anniversary, on Tuesday announced it is embarking on a "nose to tail" redesign of its interior cabins. The refresh includes new seat fabrics and materials, mood lighting throughout the plane, and memory-foam cushioning in some cabins.
