What is the minimum altitude for seat exchanges during flight?

The minimum altitude for seat exchanges during flight is established primarily for safety reasons. At 1000 feet AGL (Above Ground Level), the aircraft is typically stabilized and above the low-altitude hazards that could pose a risk if a seat exchange occurs. At this altitude, pilots have had the opportunity to stabilize the aircraft and are usually in a situation where there are more options available for managing the aircraft should any issues arise.

Conducting seat exchanges below this altitude could increase the risk during critical phases of flight, such as during takeoff or landing, where immediate communication and control of the aircraft are vital. Altitudes below 1000 feet AGL may not provide the necessary time or space to react effectively to any issue that could arise during a seat exchange.

For these reasons, 1000 feet AGL is widely recognized as the safe minimum altitude for performing seat exchanges during flight operations.
