Yes, swimming is a mandatory part of flight attendant training for almost all major international airlines in 2026. This is not for fitness, but for "Ditching" (Water Landing) certification. Trainees must typically demonstrate that they can swim 25 to 50 meters without a flotation device and tread water for at least three minutes. During "Wet Drills," you are often required to jump into a pool while wearing your full uniform (not a swimsuit) to simulate the drag of wet clothes, then successfully climb into a life raft and assist others. This is a high-value safety requirement because if a plane goes down in water, the crew must be confident enough to manage a chaotic evacuation. A peer-to-peer tip: if you aren't a strong swimmer, many airlines now offer "remedial" lessons during the early stages of training, but you must pass the swimming competency test to earn your wings and be legally cleared to work on commercial flights.
