After you have received the first provisional confirmation of receipt, some time may elapse before you receive the final travel confirmation/invoice. Especially if you make the reservation outside office hours. If you have made the reservation during the weekend, you will receive the final travel confirmation/invoice on Monday. If you make the reservation from Monday to Friday in the evening, you will receive it the next day. If you make the reservation during office hours, in most cases you will receive the travel confirmation/invoice on the same day. On bank holidays you will receive the travel confirmation/invoice on the next working day. Tip: check your spam mailbox to be sure!
