Your rights on this route
Reg. EC 261/2004, art. 7 — the amount depends on flight distance
This is the amount the regulation sets for this distance band. It is not a promise of outcome: it is owed only if the conditions are met (at least 3 hours' arrival delay, cancellation, denied boarding) and the airline cannot prove extraordinary circumstances.
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 €400 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 €400 regardless of the fare.
