You can book a trip online up to 5 days before departure. However, the sooner you book, the cheaper the trip will usually be. This is mainly due to flight prices changing. Airlines usually raise their prices as the departure date approaches. This is due to seat availability in the airplane. Sometimes, however, it can happen that an airline drops its prices – or that the price and availability of a football match changes. This rarely happens, however. In most cases, we advise you to book the trip as soon as you have decided what match you wish to attend.
