I'm normally a loyal Southwest customer, flying mainly between southern California where I live and Indiana to visit family when I have the opportunity (I less often fly elsewhere for academic conferences or the occasional friend's wedding, or short vacation in the odd circumstances where I can afford it on a grad student's income). Southwest's route network means that my parents usually have to drive three miles round-trip to Indianapolis or St. Louis to pick me up, but they're almost always so much cheaper than the flights I can find on any other airline would be to Evansville (which is like half an hour from where they live) that I still come out ahead covering their gas and (sometimes) a hotel for them (and sometimes they're happy to pay for it themselves, if there's something they want to do in Indy that day anyway).

However, flights to Evansville have been getting cheaper of late, so I always make sure to compare when planning travel so I can spare them the trip if the price difference isn't so insane as to cause a serious hardship to my budget. As it happens, I was planning a flight home for Thanksgiving, and I saw that there was somehow a flight on Delta, first class, to Evansville for about $80 more than what I would have paid to go to Indianapolis on Southwest. Between saving my parents the trip to Indy, and the extra space and legroom (not to mention meal) on the flight, I figured it was worth it, so I went ahead and bought it.

Now I'm wondering--having not done this before, does Delta enforce a dress code for revenue passengers in first class? My typical flying attire is an extremely comfortable pair of shorts and an extremely comfortable Colts or St. Louis Cardinals t-shirt (the latter of which is a few years old and slightly faded by now)--will that be a problem? Googling for "delta first class dress code" speaks of a "relaxed dress code" since 2007, but it's not clear exactly what that consists of, and at any rate it seems that it's only enforced for non-revs, but I'm not 100% sure on that.
