I’d second the nomination of the whole CLT Airport. The whole operation: angry low rent customers...had to dodge a profanity strewn near fistfight on the way to the AC the other day in a completely crammed terminal with the ceiling out presumably for replacement or we could only hope for demolition, surly unhelpful LUS agents, garbage old LUS Airbi, the apparent lack of any business travelers except those whose business involves golf and colored pants (and not the BA Galleries First type of colored pants folks). Then the ends of A and B where there are approximately 4 738/321 gates on each where there is space for about one...barely individual boarding lanes let alone any type of priority lane. Kind of like the circle AA shares with virgin at EWR...yuck...but that is a second-tier outstation and CLT is their primary southern domestic transit hub.
To echo AANTC1981: what a garbage operation. The whole LUS thing (with the notable exception of the stews, who I’ve found to be almost universally better than LAA’s) oozes nasty, cheap, and low-rent.
