What typically determines if a passenger will be "Bumped" from a flight?

The determination of whether a passenger will be "bumped" from a flight largely hinges on the aircraft's weight and balance constraints along with seating over-sale situations. Airlines often oversell flights based on historical data indicating that a certain percentage of passengers may not show up. When all booked passengers arrive, the airline must prioritize who can board to ensure safety and compliance with regulations regarding weight and space on the aircraft.

The weight and balance of an aircraft are critical factors in aviation safety. If a flight is oversold, the airline will assess the number of passengers checking in against the number of available seats. This assessment will guide decisions, ensuring that the aircraft is within weight limits while also accommodating as many passengers as possible.

Other factors, such as the time of check-in, the type of ticket purchased, and a passenger's loyalty status may influence a passenger's travel experience, including the likelihood of receiving upgrades or priority boarding. However, these factors do not directly determine the actual bumping process associated with flight capacity and safety.
