Economy Woes

One thing I hate about long economy flights is how cramped you feel sitting down, while enduring a pretty long trip. It's hard enough that some people cannot sleep on the plane, let alone sit for long periods with the possibility of getting DVT. Why can't they just all make the seats like comfy modern sofas? I can't afford to fly business class so I guess I will never ever get to experience a comfortable plane ride... Unless I win the lotto or inherit a big amount of cash, that is. Oh well, one can only dream!
