My cattle have more room in a stock trailer than you have in an airplane.  Unless you upgrade you are wedged into your seat where the space has been shrunk in order to get more paying people on board.  Combine that with the fact that people are getting larger (politically correct) and it is horrible.

The worst is when they announce not to hesitate if there is anything they can do to make your flight more enjoyable.  What the hell are you going to do? No pillows, no blankets, just oxygen and they will probably start charging extra for that soon....
