You should pay for your seats by what it costs the airlines to fly you, by space and a combination for yours and your luggage's weight. This will never happen but should.
For those of you complaining about the cattle car seating, if they made the seats more spacious every seat would cost more with less tickets being sold per flight. The current configuration is a balance of the amount of discomfort people will put up with and the price they will pay with some safety considerations. Not the airlines "fault", its market forces and consumer choice. More spacious options are available.
I have heard people say if the person reclines their seat in front of them they can't sit "in a normal position with your knees bent at 90 degrees" because they are 6' whatever. Guess what, no one beyond children sit like that. Everyone needs to put their feet fully under the seat in front of them somewhat straight. If you put a bag under the seat in front of you and can't that's on you. Travel lighter.
I always recline my seat, they are already hell enough on my back without reclining no matter the length of the flight. The only time it is reasonable to expect seats to be upright is during the rare meal service. not just beverage but the rare actually meal on long haul flights. I don't get upset at the person in front of me if they recline while I'm in a nonreclining seat in front of the emergency exits or back of the plane. I just realize I lost the airplane seating lottery.
