You can find your order and booking numbers in your confirmation email and travel document.
Your order number is available in the confirmation email’s subject and body (see red rectangle).
In the case you are not the actual traveler, you will get a separate confirmation email, in which your order number is mentioned as provider reference.
Booking number / reference – your booking number / reference is in your confirmation email next to the order number, as well as in the body of the email.
For a round-trip flight, you’ll find a booking reference for each flight.
