Not to pile on you, but just to make a further point, 13 years ago the job fair line at Atlas was not matching that of Delta's either. I understand the concern these guys have over every little detail because you know HR will be watching for the details.

By the way, I wore the same suit that I wore to my Delta interview (read very conservative). I could hardly face myself in the mirror that morning leaving for an interview without a tie on. It looked like I forgot to finish dressing. So I shoved the tie in my brief case just in case the gouge was wrong and I could throw it on in the van on the way to the interview with the other candidates. I never had to, we all were missing ties. I thought it looked ridiculous, but I was not there to make the rules. End result: Hired, wearing a conservative suit, no tie.
