I applied in a previous year and was told by the board that my assignment team told them that if I were selected they would not release me.
I wasn’t told this until after the fact and after I had spent lots of money getting some flight hours, my spouse had delayed pursuing jobs in order to wait to see if I’d be moving to a UPT base, etc. When I had originally asked them prior to applying the assignment team made it sound like it wouldn’t be a problem at all, but I could have been more specific about my situation. It sucked.
It’s whatever, the point is just that I wouldn’t gamble on this at all - every person should call their assignment team and ask if they are releasing people, better yet do it over email and get documentation.
