Ryanair doesn't actually give you the option to cancel flights, but you can change your bookings. ¹ This means that if you can't travel at all and no longer want the flight, all you need to do to cancel is not show up at the airport. You don't need to notify Ryanair and you won't be charged a penalty.

Canceling a Ryanair flight in 2026 remains a somewhat unique process because the airline generally does not offer refunds for passenger-initiated cancellations. If you simply cannot make your flight, the "standard" way to cancel is to just not show up at the airport; Ryanair does not charge a "no-show" fee. However, if you want to officially cancel to try and reclaim the Government Ticket Duty (taxes), you can do so through the "My Bookings" section on their website or app, though Ryanair often charges an administrative fee that is higher than the tax refund itself. If your plans have changed, it is usually more cost-effective to use the "Change Flight" tool, which allows you to move your booking to a new date or destination for a fee (plus the fare difference). There is one major exception: Ryanair offers a 24-hour grace period from the time of booking during which you can correct minor errors or cancel for a full refund if the flight was booked by mistake. In 2026, you can also cancel for a refund in extreme "Force Majeure" cases, such as the death of an immediate family member, by submitting an official bereavement claim form.
