I think it's hit and miss. We are under staffed especially on the 737. For Dec I think there was only about 10 or 12 reserve lines for Fos in Mdw on the 737 and maybe around 150 hard lines.
Plus we have senior folks that bid reserve for various reasons. I expect anyone who has been hired or will be hired recently will not sit reserve long at all. Short call reserve(2 hours)=14 days off. Long call(12 hours)=12 days off. We now also have open time bidding for reserve people, I'm not familiar with this and have never used it, however, it sounds like you can build a schedule for yourself to a degree. There is an L1011 class after the first of the year, I think in Jan. That's a whole different animal. You will travel to airports that don't exist.
