Reserve time at SkyWest right now is all over the place. Since we have 12 domiciles and 2 aircraft types, the range of reserve times is very big.
I was hired in August of this year on the CRJ and I finished training last month (November). I just got a reserve line for January but I am hoping to have a line at least by March with the spring break increase in flying. If that happens, it will be a total of 3 months on reserve.
On the other hand, I have a few friends that have been here for over a year on the ERJ, and they are still on reserve and are expecting at least another 6 months before they can hold a line.
The majority of reserve lines are short call (2 hours), but there are a few long call (12 hours) lines here and there. The most important thing is that there is barely any ready reserve (sitting at the airport), which is not so fun.
