You’ll find the link to the Aer Lingus website below, but you may want to read our check-in guide first.
Before you get started make sure you have the following handy;
- Your flight reference found on your invoice/confirmation - this is not your Thomas Cook booking reference and can be found on the ‘flights’ section of your Thomas Cook invoice labelled ‘airline reference’. If you're having trouble using your airline reference on your airline’s website, please check you’re using the right letters and numbers as the letters ‘I, O and Z’ can look like the numbers ‘1, 0 and 2’. The reference is a random selection of numbers and letters in any order and could also be made up of just letters.
- Your passport details - You can check in online 48 hours before you're due to depart on all European routes or 24 hours on USA flights. Online check-in will close 5 hours before your flight departs. Don’t forget to check in for your return flight too!
Check in
If you want to pre-book seats or add luggage, you’ll need to do this through the Aer Lingus website. Just click the ‘Check in’ link below and go to ‘Manage trip’.
