4/03/18 New Hire Class of 26 Inital Drop:
15 LGA
6 CMH
5 IND
April Vacancy Bid/Backfill Award for an August Move shows you can pretty much get any base you want besides MIA and IAH while in training. You can either get permission from crew scheduling to move a month or two early or go to your inital base for a couple months and then move.
Most junior MIA was 8/22/17 hire (math in public 7-8 months to get awarded, still 11-12 months before moving). IAH was a 11/09/17 hire (probably too soon to tell how IAH will trend but this data point would be 5 months to get awarded and 10 months to move).
Hopefully that helps people trying to make "which regional airline is best for me" decisions. Don't forget second best pay and best regional contract.
Cheers!
