It definitely affects your legs on certain flights. The magazine racks are plastic on some flights and they dig in your knees, the extendable tray does at times as well. You can never get a good picture on your telly screen when a seat is all the way back either, from my experience.Reclining the seats makes no difference to the amount of leg room the person behind has due to the way they’re engineered. You pay for your seat you should be able to do what the fuck you want with it. He could recline his too.
