Delta has unveiled images of prototype uniforms which are currently under development.

The carrier has been working on the new uniform collection for around a year and a half, in partnership with GPS Apparel by Gap Inc – a division of the clothing retailer which focuses on uniform design.

Delta said that Gap had collected feedback from more than 20,000 employees on future uniform designs through job shadows, focus groups, surveys and interviews, to enable it to create prototypes that are “comfortable yet elevated, modern yet durable, and above all, functional”.

The carrier said that the prototypes are “anchored in deep navy blues and rich burgundy, with accents of bright red and white – a return to a more classic colour palette inspired by Delta’s brand identity and heritage”.
