European Union – Transport. Article 3(1)(a) of Regulation (EC) No 261/2004 should be interpreted as meaning that that regulation applied to a passenger transport effected under a single booking and comprising, between its departure from an airport situated in the territory of a member state and its arrival at an airport situated in the territory of a third state, a scheduled stopover outside the EU with a change of aircraft. The Court of Justice of the European Union so held in a preliminary ruling in proceedings concerning compensation for long delays of flights.
