As 744 said, most likely you'll get CVG or ANC. I've been here a little over 1.5 years, and I could only (theoretically) hold JFK or MIA on the 747 on the most recent bid, within one or two guys from the bottom. LAX got smaller and I lost ground in HSV.

But really, what does it matter? With the exception of bidding out of ANC to avoid a long commute, you'd be better off bidding the most junior base (CVG) to maximize you bidding power.
