I just want two goddamned armrests so I don't have my elbows pinned to my ribs for a half dozen or a dozen hours. I'm an average-sized male and have no issues with legroom in economy; as long as I've got 1-2" in front of my knees I'm golden -- most seats provide more than that. I'll rant about this until the cows come home; I can pay $39 to upgrade to slightly-more-legroom class, but all I really want is some armrests. Premium economy, fleetwide, nationwide, STAT. Currently the only real PE products are on international flights (from the US perspective).
