Ryanair’s 24-hour rule allows customers to cancel or amend bookings within 24 hours of purchase, with no fees, provided the booking is made at least 7 days before the flight's scheduled departure. Travelers who may be uncertain about their intentions or who book flights well in advance will find this very helpful.
