People that chase a fast upgrade for the purpose of a fast track in life, pretty much pay in the end.

Common sense...............People leave airlines for probably 3 reasons that I can think of. 1st, they quit because it sux; next they get fired; they leave to go to a better airline.

If there is a so called fast upgrade, and none of the "better" companies are hiring very much, well that leaves me with a process of elimination. Sometimes a slow upgrade means people don't want to leave due to something favorable.

I have met several people that thought choosing an employer with a fast upgrade was a good idea. That came back to bite them in the arse.
