What this means for a claim: ATFM delays come from weather (0% here), air traffic control capacity and staffing (0%) or airport limits – causes airlines often cite as extraordinary circumstances. They are only part of the story: most long delays come from the airline’s own operation (technical faults, crew, late inbound aircraft), which this data does not show. Source: EUROCONTROL.

    How late did you arrive at your final destination?

    What counts is when the aircraft doors opened at your destination – not the departure delay.

    When were you told about the cancellation?
    When did you arrive on the replacement flight?
    Which airline operated the flight?
    When was the flight?

    How many passengers were on the booking?

    Local information

    • Ask the airline staff at the gate for the reason for the delay or cancellation and write it down; take a photo of the departure board.
    • From 2 hours’ delay (depending on distance) the airline must give you meals and drinks, and a hotel if you are stuck overnight – keep the receipts if you had to pay yourself.
    • If the airline rejects your claim, complain to the national enforcement body of the country where the flight departed (or arrived, for flights from outside the EU), or go to court.
