Ryanair does not provide a free cancellation window for its bookings. Once your flight is confirmed, you cannot cancel it for free and receive a full refund. However, Ryanair does allow passengers to modify their bookings, including changes to flight dates and times, for a fee. It’s important to remember that Ryanair’s low-cost model often means strict policies, so always ensure your travel plans are final before making a booking. For any modifications, head to the “Manage My Booking” section on Ryanair’s website and follow the steps to make changes.
