Sounds like my dh. He is 6'4''. There is no way for him to sit normally and not have his knees resting against the back of the seat in front of him. While I understand how annoying it could be for the person in front of him, how about the woman who was seated in front of him and as soon as the plane reached cruising altitude, starting slamming her seat back on his knees?? She wanted to lie back and read the paper. Well, that seat wasn't going all the way back, but she kept trying. Now, this was just before my dh had a partial knee replacement so it didn't feel very nice on his knees. Did this woman ever turn around to see what the issue was? Nope. Well, after about 3 mins of this slamming, dh leaned around the seat, tapped her on the shoulder and told her that his knees weren't going anywhere and if she continued to slam the seat back on his knees he was going to feed the newspaper to her! Okay, so not a very nice response by him. I get it, and I was horrified when he did it. But, the woman did stop.
