Rather than throw the discussion off-topic in "An Onboard Etiquette Question", I thought I would start a new topic about dress codes (the guy in the bulkhead seat who declined a move was wearing a T-shirt and no shoes).

I fly coach, and the most casual I dress is pants, shoes (not sneakers), and a long-sleeve button down shirt. My wife dresses similarly, and my little boys (except the baby) wear the same kind of outfit I do (they are comfortable clothes, so they don't mind).

Dressing decently isn't that DIFFICULT! I think that flying would be more civilized if airlines had a dress code, certainly in First Class.

The situation seems to be getting worse -- my AA non-revving relatives say that the non-rev dress code is not being enforced, even in First.

I just don't understand why someone wearing a T-shirt should be in First Class. I've seen people (in coach) wearing shorts and flip-flops, as if they were at the beach! Help!
