Can't say much about the hiring, but I may be able to help with the other questions.
1. Getting CLT isn't going to happen, as of 1 May CLT is no longer a PDT base.
2. EWN, maybe - maybe not. The last 2 classes only had 1 new hire go to EWN. 4 - SBY, 1 - SYR. 4 - MDT, 3 - CHO.
3. Reserve lines have 10 days off per month.
4. According to section 25.F.1.e: a reserve pilot is required to report from call out within:
A. 120 minutes at LGA,
B. 90 minutes at airports with busing operations,
C. 75 minutes at all other airports.
