Flight cancellation is understood as a situation where:

• your original flight is cancelled and replaced by another scheduled flight
• your original flight was diverted back to the airport of origin and passengers were transferred onto another flight
• your flight arrives at an airport which is not the final destination indicated on your ticket, unless you accepted re-routing to the alternative airport or destination or the alternative arrival airport serves the same final destination.

Redress for cancelled flights means that you will avail of the following:

• the right to choose between reimbursement, re-routing or return 
• assistance at the airport
• compensation, unless the cancellation is caused by extraordinary circumstances and if you are informed of an impending cancellation of your flight less than 14 days prior to the scheduled departure date.

EU means the 27 EU Member States (including Guadeloupe, French Guiana, Martinique, Réunion Island, Mayotte, Saint-Martin, French Antilles, the Azores, Madeira and the Canary Islands). EU rules also apply to flights to and from Iceland, Norway and Switzerland.

EU rules also apply to flights from the UK to the EU operated by an EU carrier, unless you have already received compensation or benefits under UK law.
