For a Delta flight attendant interview in 2026, you must wear professional, closed-toe business shoes that align with their strict "Welcoming, Elevated, and Caring" brand image. For those wearing a feminine-style suit or dress, this means classic black pumps with a heel height between 1 and 3 inches, or high-quality black flats. Sling-back shoes are sometimes permitted if they are professional, but open-toed shoes, sandals, or athletic footwear are strictly prohibited. For those wearing a masculine-style suit, black leather Oxford or Derby shoes are the standard. The shoes must be polished and scuff-free. Remember that you will likely be standing and walking during the "Reach Test" and group exercises, so comfort and stability are just as important as the professional aesthetic.
