Questions referred

Is Article 5(3) of Regulation (EC) No 261/2004 1 of the European Parliament and of the Council of 11 February 2004 establishing common rules on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights, and repealing Regulation (EEC) No 295/91, to be interpreted as meaning that the operating air carrier can rely also on such extraordinary circumstances which did not occur on the flight booked by the passenger but on a — not immediately — preceding flight on the same day using the aircraft that was supposed to be used for the flight booked by the passenger as part of a flight diagram?

Is Article 5(3) of Regulation (EC) No 261/2004 of the European Parliament and of the Council of 11 February 2004 establishing common rules on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights, and repealing Regulation (EEC) No 295/91, to be interpreted as meaning that ‘all reasonable measures’ which the operating air carrier must have taken in order, in the event of extraordinary circumstances, to avoid an obligation to pay compensation in accordance with Article 7 of that regulation must be aimed merely at avoiding the ‘extraordinary circumstances’ (in this particular case, the allocation of a new (later) air traffic control slot by the European air surveillance organisation EUROCONTROL), or is the operating air carrier also required to take reasonable measures to avoid cancellations or long delays themselves?

If the operating air carrier is required to take reasonable measures to avoid long delays themselves, is Article 5(3) of Regulation (EC) No 261/2004 of the European Parliament and of the Council of 11 February 2004 establishing common rules on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights, and repealing Regulation (EEC) No 295/91, to be interpreted as meaning that, in the case of the carriage of passengers on a route consisting of two (or more) flights, the air carrier must, in order to avoid an obligation to pay compensation in accordance with Article 7 of that regulation, merely take reasonable measures aimed at avoiding a delay to the flight which it is due to operate and which is subject to possible delay, or that it must also take reasonable measures to avoid a long delay for the individual passenger at the final destination (for example, by examining the possibility of rebooking the passenger onto another flight)?
