I upgraded Capt. of a jet in 8 months.
However that was at Independence Air.
My point is this young jedi, what upgrade time is does not matter. Say someone tells you that its 8 months, well 8 months in the airline industry is like dog years. For example, go to MSN money and look at a graph of JetBlue stock price for the past 3 months. It has gone straight down in only 3 months!
Time is very short and costs have a dramatic impact on the airlines. This being said, with an 8 month upgrade the only people that will upgrade in 8 months are those who were hired 8 months ago. 8 months from now, upgrade is anybodies guess. You can never count on upgrades, go to a place that if you get stuck in the right seat its not that bad.
If you want more advise PM me, and good luck.
