Last year on a flight from Hawaii to the US I was told by the flight attendant that I was too tall (6'2") to fly coach and that if I was in coach on another of her flight, I would be removed. She said that the woman in front of me had the absolute right to recline all the way and that it was up to me to adjust myself to a position where she could do so.If my legs were too long, that was my problem.
It was rather annoying to be chastised for being too tall (I'm hardly a giant) when I have had to share a quarter of my rather narrow seat with an obese person (where I was chastised for not understanding that passengers of size must be accommodated. Guess people over 6' tall need to start a group to get recognized as protected group so we get priority over the lean-back crew.
Oh, and after she could not lean back all the way, even with my legs twisted over to the side in very uncomfortable position, the attendant took pity on me and moved the lady in front of me to first class, but then reminded me that she had better not see me in coach again. (She won't. I'll never fly United again.)
