Yes, they can elect to 'bump' you off the flight involuntarily. You would then be due even more compensation. What you don't know is if you would be the person selected to be bumped until it happens. How much does it cost to change a flight with Spirit Airlines?

Like most commercial airlines, Spirit Airlines is permitted to "bump" passengers—a practice known as Involuntary Denied Boarding—when a flight is oversold and there are more passengers than available seats. According to Spirit's 2026 "Contract of Carriage," if a flight is overbooked, the airline must first solicit volunteers to give up their seats in exchange for compensation (usually Spirit flight vouchers or cash). If enough volunteers are not found, Spirit determines who is bumped based on "boarding priority," which often prioritizes those who checked in earliest or have specific status. If you are involuntarily bumped, you are legally entitled to Denied Boarding Compensation (DBC) under U.S. DOT rules, which can be up to 400% of your one-way fare (capped at approximately $1,550 to $2,150 depending on the length of the delay). However, you are not eligible for compensation if you are "bumped" for reasons such as being late to the gate, safety/weight balance issues on smaller planes, or disruptive behavior. Spirit aims to minimize these incidents, but they remain a legal "last resort" in the budget airline industry.
