On the 747 to SF, you get to sit upstairs and share toilets with business class, plus it says you get leg rests as well as foot rests. It says you get 50% more recline than economy which sounds pathetic.
on the 777 to lax you get the weird seats and a bean bag, and I guess the same recline but it appears that you share toilets with economy.
I am a short, thin woman. The leg rests on the 747 sound like the best bet to me. Am I missing something? I don't think I can face economy any more. By half way thru the night my legs are killing me.
