Official Ryanair policy states that the airline does not overbook its flights. Unlike many traditional legacy carriers that sell more tickets than there are seats (banking on "no-shows"), Ryanair’s low-cost model relies on every seat being paid for and filled. However, in 2026, passengers may still be "denied boarding" for non-commercial reasons, such as an aircraft swap where a smaller plane is substituted for a larger one, or for weight-and-balance safety restrictions due to extreme weather. If this occurs, Ryanair is legally bound by EU261 (or UK261) regulations, which require them to seek volunteers first. If you are involuntarily bumped, you are entitled to a full refund or a replacement flight, plus fixed cash compensation of up to €600 depending on the flight distance. While rare, these "operational overbookings" are the only time a passenger with a valid ticket would be denied a seat, making Ryanair statistically one of the least likely airlines to "bump" you for profit-driven reasons.
