I had the same issue ... trying to max out terminal and PTDY to move availability to the left while also budgeting LV to attend interviews & job fairs. I would definitely burn days to attend a high-payoff job fair like WIA or OBAP or to interview with a top-tier airline. I wound up getting a class date starting 13 days after my last mil day, so wasn't on ice like some recent AA and DAL guys, but I was hired by airline X while in training at airline Y and it was nice to know I had a plan B available if necessary.
