Well as for the bases this is what our april EMB class (10) got (Top 6 in the seniority got FAT, then 3 MRY and the final guy got LAX). I am starting IOE from PSP Friday on a nice 4 day trip, then a week off and do 2 (2 days) back to back.
But from what everyone has told me thru my training, unless there is movement from awards, you should expect FAT. Some in my class wanted SLC and they were told it would be a few months before they could possibly expect that. But bid ALL THE CITIES in order of preference, and you might get lucky and get the base you want.
Either way I am really having fun and look fwd to my first revenue flight of IOE. (PSP-LAX-MRY-SFO-ACV-SFO-SMF)... Phew will be a long day.
