Their TripAdvisor reviews are actually pretty good for a low-cost airline. What exactly are you concerned about? For such a short flight I don't even see the point in having facilities, etc.
Hi, thanks for your reply. I don't care about fancy meals etc. just want to get from A to B without too much delay. I read said that people got bumped off and that flights didn't go at all, so people were stranded. I think they only fly to Santorini one day a week so if it was cancelled, it would be really hard to get to Santorini quickly.
