I'll be flying first class from Kansas City to Orlando this fall. This'll be my first time experiencing this, as I typically fly coach. This time around I found a good deal on FC seats and just wanted to experience it at least once.
Any suggestions on typical dress for first class? I know this sounds silly, but I didn't know if it's considered proper etiquette to dress more professionally or at least nicer when sitting up front?
EDIT: I understand that domestic First Class is not the same as Intl. I'm not expecting fancy lie-flat seats, or walled-off suites. I know the seats are bigger, and you get to board/de-plane first. What I'm asking, is do people tend to dress nicer than, say, shorts/t-shirt when riding up front?
UPDATE: the plane(s) I’m flying on are B737-800s. I have one short layover in ATL both ways
