im of the opinion that you should look presentable regardless of where you are, so i generally wear at least nice jeans and a polo when i fly. im generally appalled at how people dress in public anywhere (see peopleofwalmart.com), but especially when you are going to be crammed together in a metal tube.

im not saying it's right to assume someone is or is not in F because of appearance, but im not surprised that it's a question. we have all seen people with zone 5 try to board with zone 1, so why wouldnt these same people try to check in at the shorter line (for F)?

sorry if you felt singled out, that's not cool... but my hunch is that some of the people who have posted here would be .....ing if a "slovelnly" passenger wasn't booted from the F line if s/he didnt belong there
