answer:I have never flown Iberia, but I know people who have, and I did not here overly negative comments. People speak badly about Al Italia and my father recently, and I 15 years ago did not have a bad experience, but it is not over the top fantastic exceed your expectations either. I have heard that Lufthansa is really great, and I flew JAL and was very impressed. My guess is since it is students they won’t know the difference, unless they travel a lot themselves. The only concern I would have is if they have a bad safety record, I would not give a minute thought to the service, especially if they are on a red eye.
