What changes of a scheduled departure time qualify as cancellation?

On 21 December 2021 the European Court of Justice (ECJ) rendered two decisions regarding the question whether certain changes of a scheduled departure time qualify as cancellation within the meaning of Article 5 of Regulation 261/2004.

In case C-395/20, a flight from Düsseldorf to Antalya that was initially scheduled to depart at 13:20 was postponed to depart at 16:10. The ECJ decided that because the departure time was postponed by less than three hours, the flight must not be regarded as being cancelled.

In case C-263/20, a flight from Palma de Mallorca to Vienna that was initially scheduled to depart at 14:40 was brought forward to depart at 08:25. The ECJ decided that because the departure time was brought forward by more than one hour, the flight must be regarded as being cancelled (leading to the consequences stipulated in Articles 7, 8 and 9 of Regulation 261/2004).

On a side note: in this case the ECJ also stated that it is not sufficient for an airline to merely inform the intermediary through which a flight was booked about the changes of the scheduled departure time two weeks in advance to comply with Article 5 (1) (c) (i) of Regulation 261/2004 and to avoid being obliged to pay a compensation – even if the passenger´s contact details were not disclosed to the airline.
