Cancellation
If you cancel, you have the same rights as if you were denied boarding.
In the case of rerouting where the expected departure time is not until the day after the scheduled departure time of the canceled flight, you are also entitled to hotel accommodation and transportation between the airport and the place of accommodation.
There is no entitlement to compensation if the airline proves that the cancellation is due to extraordinary circumstances that could not have been avoided even if all reasonable measures had been taken.
Claims can also be excluded if you have been informed of the cancellation at least 14 days in advance or the flight times of your replacement flight differ only slightly from those of the original flight.
