My airline has changed my flight to one that leaves four hours later. Can I expect compensation?
If your flight’s cancelled or delayed more than five hours, and the European Union’s Denied Boarding Regulations apply, the airline should offer you a refund or an alternative flight. In some circumstances, you may be entitled to compensation if your flight’s cancelled. The refund is of the flight cost only, not the holiday price if the flight is part of a package holiday.
If the European Union’s Denied Boarding Regulations don’t apply, you are entitled to the assistance and recompense set out in the airline’s conditions of carriage or the tour operator’s booking conditions.
