We have booked a FlyOne Armenia flight 3F 928 from Paris (CDG) to Yerevan. It was originally scheduled to depart at 16:50 on Aug 19, and arrive at 23:10. However, today (Aug 17) at 10:39 (Paris time) I received an email that the flight has been rescheduled to depart at 20:00, and arrive at 02:20 the next day.
Firstly, am I entitled for compensation according to EC261?
I understand that, because it is a flight from EU by a non-EU arline, the EC261 should apply. However, it is not clear whether this reschedule constitutes a delay. Technically, it is not a delay, they have warned me in advance. At the same time, 2 days notice is obviously not enough (I would not choose a flight that arrives after midnight in the first place), and if rescheduling was a EC261 loophole, then the airlines would never delay, just reschedule, — so I hope that it counts as a delay. Also, the text of EC261 specifies that to claim the compensation we should arrive to the airport at proper check-in time, and it would be strange to arrive at the original check-in time (although we can do this...).
Secondly, if I am entitled, then how should I apply for it? Obviously I will start by emailing the airline, but the airline is notorious by not replying to emails. Should I file a complaint with some French authority?..
