Most airlines do not have minimum or maximum weight requirements either. Instead, they require that flight attendants' weights be proportional to their body type. Flight attendants must be able to sit comfortably in the jump seat and easily maneuver through the aisles of an airplane.

In 2026, airlines do not have a specific "weight limit" in pounds or kilograms, but they do enforce "proportional weight" and "Body Mass Index (BMI)" requirements for safety and professional appearance. Most major airlines, including Emirates, Qatar, and IndiGo, require flight attendants to have a BMI typically between 18 and 22 or 25. The primary reason cited by airlines is "safety and agility"; crew members must be able to move quickly through narrow aisles during emergencies and fit through over-wing emergency exits. Additionally, there is a functional requirement: you must be able to sit in the "jumpseat" and fasten the harness securely without a seatbelt extender, as most aviation authorities do not allow extenders for crew. While the industry has moved toward more inclusive hiring practices, the 2026 standards still emphasize a "neat, fit, and groomed" appearance. If a crew member's weight significantly changes after they are hired, some airlines may place them on a "health and fitness" program to ensure they remain capable of performing their safety-critical duties without physical restriction in the tight confines of the aircraft cabin.
