I've received another confirmation showing the balance, have I been charged twice?

If you have received more than one confirmation, please check the booking reference at the top of the document which will show a booking reference made up of two letters and five numbers, or two letters, four numbers and the letter x. For example, AB12345 or AB1234x. The most common reason for a customer to have received more than one confirmation is because the booking has been changed in some way, i.e., passenger names, or dates of travel.
