Technically, you can cancel a Ryanair flight, but in 2026, the airline’s "no-refund" business model remains strictly in place. Ryanair flights are generally non-refundable if you choose not to travel. If you cancel, you will not receive your money back unless you have a "documented" emergency like a death in the immediate family or a serious illness (though even then, they often offer "travel credit" rather than cash). However, you can change the dates or route of your flight up to 2.5 hours before departure for a fee (typically €45 per person, per flight) plus any difference in fare. For 2026 travelers, the "high-value" strategy is to only request a refund of Government Tax, which you can apply for within one month of the missed flight. If Ryanair cancels the flight themselves or it's delayed over 5 hours, you are legally entitled to a full refund under UK/EU 261 regulations.
