Airlines generally suck especially if you're tall. I think I'll avoid Northwest, clearly they don't give a shit if you get your knee busted. It's very important for short little fucks to recline. And Delta I can tell you doesn't care if you complain...after have a bruise from one of their seats that lasted three weeks they didn't even apologize. Delta for the record has the least legroom on any plane so far. Also the row behind the emergency exit has the least room on any plane especially Alaska.
It amazes me that they seem to think you're weird when you check in to ask for a row with more legroom. I think people generally agree that seats are too narrow but when you can't fit in the seat and put your legs in the aisle (which I've physically had to do) the flight attendants get quite hostile. Just where exactly am I supposed to put them? It's not like I have additional joints I can just fold up, and my legs don't come off. I understand they need to push the cart down the aisle so they can give you a thimbleful of coke and a single peanut sealed in a wrapper but I still can't fit.
More protein in the diet means people get taller every year as food is increasingly more availible. But plane seats get smaller.
