I will also never ever, ever never, never ever fly on a red eye that connects through Vegas. That was the weirdest flight I've ever been on.
I'm a big guy, but not so big I can't fit into an economy seat with the armrests down. So I've got to wonder why people a foot or so shorter than me have to have the seats in the full recline position when I can sleep with them in the half recline position out of courtesy to the people sitting behind me.
