The current rumor around here seems to be more internal upgrades vs DEC.
While there are not any guarantees and you have to jump through a lot of hoops such as interviews and assessment flights, I have flown with several pilots starting PSA exams in preparation for the above after 2 years on the line....all in all it is 3 years best case scenario but still not bad.
I have flown with many that meet the said requirements and still waiting???
Possibly training records or employment history can slow you down.
