Average time running at about 24 months at most regionals, and the ones that are not are catching up quickly. One of my good friends flies for Eagle, he was telling me that they're anticipating time to come down significantly in the next couple of years to as low as 3-4 years...for eagle that's low!
Like a couple of folks said here, enjoy the right seat, cause it goes by quickly and before you know it you'll be there.
