Any delay of an aircraft that exceeds the three hours recorded on arrival, is compensable, as the cancellation and overbooking of a flight. Passengers are also entitled to a refreshment (meal + snack) from two hours late.
An allowance between 250 and 600 euros can be claimed by passengers who already have their boarding passes. They must quickly consult Air Indemnité establishing in their favor a claim file to defend them against their operator.
No doubt, only flights that are provided by Air Cairo from a European airport that can be compensated because the Egyptian carrier does not belong to the European Union.
