Some of the factors that airlines consider when deciding who gets bumped include check-in time, fare paid by the passenger, and frequent flyer status. It is important to note that these criteria must not be used in a way that prejudices or disadvantages any passenger unjustly or unreasonably.
Only about 5,690 passengers of the more than 195.2 million enplaned in early 2023 were bumped, DOT data shows. It's far more likely that passengers will volunteer to give up their seats, which may allow you to catch your flight after all.
Right before a pilot lands, they will typically make an announcement to the passengers informing them that the plane is beginning its descent and to prepare for landing.
