There have been several discussions online lately about this but I hadn't seen any here so I was curious what folks thought. When sitting on an airliner in coach/economy should you be allowed to recline and how far? Are you entitled to do so if the seat is designed to let you recline? Should you ask the person behind you if it's ok? Should you be allowed to use one of those knee defender devices?
I think we all agree that planes have tight seating in general and understand that to get room you usually have to pay significantly more money.
Personally I never recline and even if I did I would probably ask or at least only recline minimally if someone was sitting behind me. I believe they need to do some engineering to see if they can come up with a seat design that allows some reclining without compromising another passenger's space or use of their tray and without using up very much space on the plane.
