If you’ve recently booked a Ryanair flight and now need to cancel, you may be wondering, “Can you cancel Ryanair within 24 hours?” Unfortunately, Ryanair doesn’t allow free cancellations within 24 hours of booking. Once you’ve confirmed a booking, the flight becomes non-refundable. However, the airline does allow certain corrections to your booking within 48 hours, including changes to passenger names or flight details, though fees apply.
