Count me among those who prefer to dress comfortably on flights, especially TATL when I'm trying to get some sleep. I've got a DL reserve card, but I've never had the desire to visit any CRC. Usually it's because my layovers are too short to make it worth it, but also I'm nervous about running smack into an elitist country club attitude in there. If being dressed comfortably means hanging out with the riff-raff fighting over a wall plug in the gate house for my laptop, so be it.
