I'd pick that everyone has to sit straight up, period! Never fails, as soon as I sit down the person in front of me reclines and I can't get out of my seat without holding onto the back of their seat. They always turn around and glare at me but how about me having my meal tray titled and my food slipping all over the place. Last flight to CA DH thought we'd outfox them buy requesting the seats in the middle of the plane by the exit door. There used to be a wide space by that door so you could stretch out your legs. Well, that's gone as they put 2 staight up seats in that space and if we had an emergency I would have been the person to open the hatch and help everyone to get out. May in Jersey
