One time flying out of Detroit to go to NAGOYA, we got upgraded. This is how it happened. There was this guy from NW getting prepped for the travelers. I was standing around and approached him and just struck up a conversation. It was more like in the lines of how it was like to work in Detroit with NW and I told him I was out in the Pacific working for CMI that we were on vacation in the states. He then just like that, out of the whim, looked in his computer and UPGRADED US out of the kindness of his heart. He must have thought I was a good guy. I didn't have being upgraded at all on my mind and didn't expect it at all. He saved us a long long long flight by putting us up. Should have taken his name and mailed him a card or something.
