zertohero, you are right. You probably have a fair chance if you are near to hours now. I expect there will probably be about 200 more f/o's promoted before the end of the deliveries, but after that they will become a rare event. In the old days, it was common to fly the right seat for a long time before you got a chance at command, and it seems these days are back.
Even if and when the industry picks up, it is full of young captains who aren't retiring anytime soon. Mind you, in 30 years or so when all these guys reach retirement age, there will be a big shortage then.
