You will receive your ticket by email after booking. Always carefully check that your name matches the name on your passport. On the ticket you will find your Travel2be booking code, as well as the airline booking code. You will need the airline booking code along with your passport details to check in online via the airline’s website 24-48 hours before departure.
There is no need to print out your ticket, but make sure you store it in your files so you can access it if you need to. You can always check your ticket details at My Trips.
