Let me put it to you like this...
Q: How long does it take to upgrade at any company?
A: As long as it takes for those above you to move on!!!
C'mon, it will be a long time. Chances are you will be able to bid a position out of ONT before you are able to bid a Turbine run out of BUR. Right now, my best guess would be 2-3 years. At AMF, if you want to upgrade quickly, the key is bidding the next aircraft at any base it may come available.
FG
P.S. Upgrades at Pinnacle are running just under 3 years. Do you have your app in yet?
