How long can you sit on a plane at the gate before it becomes uncomfortable or inconvenient?

The amount of time you can sit on a plane at the gate before it becomes uncomfortable or inconvenient varies for each person. Factors such as seat comfort, legroom, and personal preferences play a role in determining how long one can comfortably wait on a plane. Some people may start feeling uncomfortable after an hour or two, while others may be able to tolerate longer waits. It is important to move around and stretch periodically to prevent discomfort during extended periods of waiting on a plane.
