In 2026, the policy on beards for flight attendants remains highly airline-dependent, though it has become significantly more progressive than in previous decades. Most major US carriers—including United, Delta, and American—still enforce a strict "clean-shaven" policy or allow only very short, well-groomed mustaches for male cabin crew. This is often cited as a safety requirement to ensure a tight seal for emergency oxygen masks, based on older FAA studies. However, international airlines and some US budget carriers like Air Canada, British Airways, and Allegiant Air now permit well-groomed beards. If you are flying in 2026, you will notice a "mosaic" of standards: while European and Canadian crews may sport facial hair, US legacy crews typically maintain the "traditional" clean-shaven look to comply with their specific corporate uniform guidelines.
