Delta Air Lines recently released a memo outlining detailed appearance standards for current and potential flight attendants. The guidelines cover grooming, attire, and accessories, with a notable reminder: wearing proper undergarments is mandatory, though they must remain invisible. The two-page memo stresses the importance of flight attendants representing the Delta brand professionally, as they are the face of the airline.

According to the memo, Delta expects flight attendants to embody the company’s values by providing an exceptional customer experience that reflects safety, pride, and graciousness. The airline emphasized that this image starts the moment they put on their uniform.

Key points in Delta’s grooming and appearance guidelines include:

Hair should be naturally colored, with no bold highlights or artificial hues.

Long hair must be tied back and pinned if it extends beyond mid-back.

Eyelashes should maintain a natural look.

Nail polish must be neutral, with bright colors, glitter, or intricate designs prohibited.

Tattoos must be covered, but bandages cannot be used for this purpose.

Only a single nose piercing is permitted, with subtle gold, silver, or diamond-like studs allowed.

Each ear may have a maximum of two earrings, smaller than a dime, with no hoops permitted.

Visible body piercings, aside from the nose, are not allowed.

Clothing must maintain professionalism, with skirts and dresses falling at or below knee length. Athletic shoes are not allowed; flight attendants are required to wear closed-toe flats, heels, or sling-back shoes. Men must wear a tie with a button-down shirt as part of their uniform.

The memo also highlighted a strict no-tolerance policy for behaviors such as profanity, gum chewing, and the use of phones or earbuds during interviews.

Delta concluded by assuring accommodations for religious attire unless it poses a safety risk or undue burden on the company.
