1. It depends on how much hiring we do in the next few months. The most senior person I know that can't hold a line has been here since last May. He wants to be based in CVG, where we have only 6 lines, so he has to sit reserve until someone upgrades. The most Jr. person I know that holds a line was hired back in March, and the line is out of DAY (our Jr. base). The last new hire class all went to TYS. I would plan reserve for atleast 3 possibly upto 12 months (most likely not more than 3 if we start hiring again) depending on base, fleet growth, and hiring. Wish I could be more specific.
2. CVG is all out and backs. PIT tends to be the commuter base. DAY and CAK usually have atleast one out and back line. I'm on the scheduling committee and to be very honest the lines change every month. All of our flying is given to us by USAirways mainline and changes from month to month and then we just try to put it together the best we can. The schedules for July seem to be stuff that mostly starts very early and ends very late, or atleast thats what some guys are saying. If I were you, I would just drive to Dayton when I get a line.
About the jets: What Skeezer said is pretty much the truth, just watch the news for any anouncments from USAirways ALPA or Mgt. Once those guys get the scope worked out then we will know a little bit more about who gets them, when, and how many. Right now no body knows anything, or if they do they are not telling the rank and file pilots of PSA.
Good luck.
