This is a cheat. You toke money from me but you didn't give us my ticket. When we reached the airport security said I don't have any flight booking while I had booked a ticket and your careless behavior I have to get another flight. Gave me back my money or I'll do a police case.

Very ordinary experience. I suppose I should be grateful that I was flying to Barcelona and back to Boston for the price that I did. No food included during the 8 hour flight from Barcelona to Boston. What? Not even a snack? And that makes even less sense when you take into account that food was included during the flight from Boston to Madrid. Everything else was ‘meh’. Will be trying to avoid this airlines if I can. But sometimes the price trumps everything else.
