I find it amusing to read the debate over a couple of lousy inches. With seat pitches and widths at an all time low, I find absolutely zero difference between (UA's) 727, 737, 757, A319 or A320 in coach. They all suck. I have a "favorite" seat on each that eases the problem, but having been stuck on every single one of these planes in coach in the past 24 months, I'm telling you there's just not that much of a noticible difference (aside for the shabbiness and brightness in the cabin).
