In its judgment of December 21, 2021 (joined cases C-146/20, C-188/20, C-196/20 and C-270/20), the Court of Justice of the European Union clarified that a flight that is brought forward by more than one hour is to be considered cancelled. This means that flights that are brought forward by more than one hour can now also give rise to a claim for compensation within the meaning of the Air Passenger Rights Regulation (Regulation (EC) 261/2004).
