Make sure you have the following handy, as you might need all or some of it!

  • Your Airline reference found on your Thomas Cook invoice/confirmation (This is not your Thomas Cook booking reference.

The reference is a random selection of numbers and letters in any order and could also be just letters.
  • lead passengers surname, 
  • The email address (the one your confirmation was sent to), 
  • Your flights dates,
