I feel if you weren't supposed to recline, then the seats wouldn't be able to recline.
I am very nervous flying and try to sleep. I can't sleep sitting straight up like a board. and after a couple hours of sitting staright up my hip will be in pain.
when I can't sleep, I put mybook or crossword puzzle on the tray and never have ahd a problem with it, or with a drink or coffee on the tray when the person in front of me is relined. a pad or tablet will fit nicelyt, too.
now maybe a laptop won't, but after all, it is called a LAP top, not a TRAY top.
speaking of trays, on the way to Calif. the guy with his tablet behind me kept getting irritated everytime I moved a bit and the tray (connected to my seat) jiggled a bit. when the pilot announced we were flyng over the Grand canyon I got up quick to see over the other 2 people and he was like "OH COME ON!!!"
but on the way home, I was working my crossword puzzle and the person in front of me told me to stop jiggling her seat. now how hard can I be writing the letters> lol
anyway, it is really the airlines' faults for jamming so many in so close. we all know the situation.we are all sharing very little space for a few hours. if these tight quarters are really irritating to you, then you should pay for a first class seat.
