Flight attendants sit on their hands during takeoff and landing as part of the bracing position, helping to prevent injury and ensure a quick response in emergencies. This posture keeps their body stable, reducing movement during turbulence or impact, allowing them to assist passengers immediately if needed.

However, this practice is a personal preference rather than a strict regulation. Some flight attendants, like Henny Lim, follow this method, while others, like Erin Thomas, prefer resting their hands on their laps to appear calm. Regardless of hand position, the key is being in the brace position to stay prepared for any emergency.
