What this means for a claim: ATFM delays come from weather (25% here), air traffic control capacity and staffing (36%) 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.

    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.
