As a comparison, let me describe a situation I encountered the other day with the "kind" AA.
Wife and I trying to take a quick trip to see relatives for the holidays. All flights on company metal way oversold. Got to the airport a bit late, inadvertently picked the longest, slowest security line possible, get to the gate 5 minutes after boarding began. She's listed but I'm not because I want to CASS (free that way). She's already been cleared and they give her a seat. I tell the gate agent I know I'm late and that she's busy, but if there's any way they could help me out it would be great. A supervisor comes over, spends 5 minutes on the computer, and they give me a 1W. No "too busy," no "can't help you," no "better luck next time." Just a smile, a Merry Christmas, and a boarding pass. I feel comfortable saying that scenario most likely would have played out differently at our place.
