I booked a Ruinair flight to Seville back in February. In March they changed my flight by 12 hours, necessitating me spending fr an extra night in Seville (all other flights were by then more expensive) AND arriving in the middle of the night instead of in daylight.
Then, two weeks before I was due to fly they made the flight later by half an hour.
Everyone asked me why on earth I'd booked with Ruinair.
I said I felt I needed to find out for myself if they really were that bad or not.
My son (quite fairly) asked ""Would you put your foot into a crocodile's mouth to find out if it bit?"
NEVER AGAIN!!!!!
I've flown with Easyjet many times and they're a quite ok airline. (Thank God I'm flying home with them.)
Air France has tried to destroy my baggage twice, and succeeded the second time, so give them a miss too. Their baggage handlers don't have the best reputation. Also, they bumped me from a flight, so although I got an earlier one with them they may not be as reliable as some.
