I'll never forget an ASA flight that I was on a few years ago. It was running about 30 minutes late, connecting into DL's last bank of flights at ATL. Once we arrived, the FA blocked the pax from exiting saying she was waiting for carry-on bags to be unloaded. Well, duh, some pax didn't have carry-on bags and needed to RUN to their connecting flights!
After letting the pax off, the FA said that she didn't understand why they were so pushy! The FA didn't even seem to understand the basics of a hub airport.

ASA -- what a great airline!
