There is one available right now. It closes on Monday the 21st at Noon Central time.

Bid what you want. Want what you bid. Careful what you bid for, as you just might get it!

Vacancy bids have generally been coming out about once per month, or slightly less frequently, so if you don't get a lateral on this bid, you will likely have another opportunity before you leave training. I don't think you will have any issue getting to SFO, the issue you are going to have is deciding how quickly you want to upgrade to a Widebody, as those bids will be coming soon there as well.
