I was flying to Europe on NW last spring with a team of 5 other people. We were in coach. I decided at the last minute that I just couldn't handle it and upgraded. I felt very guilty about it and planned to sneak on to the plane. I knew it was bad karma. Guess what my punishment was? The other five ALL got operational upgrades. If I hadn't tried to sneak the upgrade in, I would have gotten it for free.
