Your rights on this route

Up to 1,500 km250
1,500 to 3,500 km400
Over 3,500 km600

Frequently asked questions

When is compensation due?
When the flight reaches its destination at least 3 hours late, is cancelled with less than 14 days' notice, or you are denied boarding due to overbooking. On this route the amount is €250 per passenger.
What counts as extraordinary circumstances?
Events outside the airline's control: prohibitive weather, air traffic control strikes, medical or security emergencies. An ordinary technical fault or a strike by the airline's own staff usually does not qualify.
How long do I have to claim?
In Italy the limitation period is 2 years from the flight date. In other European countries it can run to 5 or 6 years, depending on the law applicable to the carrier.
Does it apply if my ticket was cheap?
Yes. Compensation under Reg. EC 261/2004 depends only on route distance and the disruption suffered, never on the ticket price. On this route it is €250 regardless of the fare.
