To amend or cancel your Ryanair flight you'll need to contact them directly, as we don't have access to your booking once it's been made. Click here for Ryanair's webpage about making changes. Any charges for the amendments you make need to be pay directly to Ryanair. You'll also need to tell us about any amendments so we can make sure they won't affect any other part of your booking, such as your hotel or transfer.
You will also need your airline reference (NOT your Thomas Cook reference) and YOUR email address used at the time of booking your holiday. These are both found on your invoice. The airline reference is in the Flights section shown below).
Should Ryanair make any changes, they'll email you themselves. Just make sure you let us know about any changes, too, so we can check the rest of your holiday isn't affected, such as your transfer or hotel reservation.
