What if my flight is cancelled?
If your flight is cancelled or you are denied boarding because it is overbooked, you will be entitled to compensation unless the airline can prove this was a result of "extraordinary circumstances which could not have been avoided even if all reasonable measures had been taken".
These could include things like strikes, bad weather and political instability.
If the airline is to blame you will be automatically entitled to a full refund and a return flight to the first point of departure, or to have your journey rerouted.
Compensation for a delayed flight varies depending on the length of your flight and how long your arrival at your destination is delayed as a result of you being rerouted. The amount to which you are entitled is as follows:
· €125 (£99) on a journey of up to 1,500km delayed by up to two hours
· €250 on a journey of up to 1,500km delayed for more than two hours
· €200 on a journey of 1,500km-3,500km delayed by up to three hours
· €400 on a journey of 1,500km-3,500km delayed by more than three hours
· €300 on a journey of more than 3,500km delayed by up to four hours
· €600 on a journey of more than 3,500km delayed by more than four hours
If your journey is delayed as a result of a cancelled flight you should also receive assistance at the airport in the form of free meals and refreshments, telephone calls and, where appropriate, hotel accommodation.
When cancelling a flight or denying boarding, the airline must provide each passenger with a leaflet outlining their rights and the amounts of compensation due.
