I was just going to ask about that...So CA's bid the trips they want first by location, commute and so forth.. and then FA's/FO's/SO's bid after capt. bids are out but can also base their bid on captain preference as well...Here the CA's bid, and then the FA's and FO's bid about a week later. So as an FO you can "sorta" pick who you fly with if you want to bid that way, although I never put that much energy into bidding - way too much work.
that's interesting, i didn't know that's how it worked.
