If you’ve ever glanced at the cabin crew during takeoff or landing and noticed them sitting with their hands tucked under their thighs, it might seem a bit odd at first. But this isn’t about comfort—it’s a deliberate safety position used in aviation.

These phases of a flight are considered the most critical, as the aircraft is closest to the ground and pilots are handling complex maneuvers. During this time, flight attendants adopt a specific brace posture: sitting upright with a straight back, feet flat on the floor, and hands placed palms-up beneath their thighs. This position helps keep the body stable and controlled.

The goal is to reduce the risk of injury. In case of sudden turbulence or a hard landing, securing the arms prevents them from moving uncontrollably and getting hurt. By staying protected, crew members are more likely to remain able to assist passengers immediately if something happens.

At the same time, this posture keeps them alert. Flight attendants use these moments to observe the cabin, stay focused, and be ready to act quickly if needed. Unlike passengers—who are told to brace for their own safety—the crew must be prepared to move and help others right away.

So if you see this posture during your next flight, know that it’s not random—it’s a trained safety technique designed to keep both the crew and passengers safe.
