One more interesting story...

I was on a DL flight home from Paris to LA in Business class, connecting in JFK (old 3 class config.). On the JFK - LAX portion, I was separated from my girlfriend. She had the aisle and I the other side of the aisle. I politely asked the gentleman seated next to me if he wouldn't mind switching with her, so I can sit next to my girlfriend. Well, what a pain her was. He insisted he was comfortable, his bags were on his side of the overhead bin (I even offered to move them for him), and simply refused to move. (I guess he didn't want the person on the window side to step over him)

Well, I took my seat, then a gentleman came up and said he was in the same seat as I was. Funny, 2 people in the same seat? Then, the red coat came and took my boarding pass and gave me a new one, seat 1C. Operational upgrade to first class. I looked at the gentleman who wouldn't trade seats, smiled and offered my first class seat to the gentleman who was to be in my original seat. I guess sometimes you never know.
