The last vacancy award had some MSP saab positions, so it's not impossible. The 900 spots if vacant will likely be filled with current 900 FOs moving bases, so those positions won't be available when you bid.
There are 24 spots in the Nov 3rd class... 8 saab and 16 900. The vacancy award will be posted internally by Oct. 27 at 5pm. At that point the dust will have settled and the open spots for new hires will be known. Check back here at that point, I'm sure someone will post what the positions are. Welcome aboard.
