BNA Base publicly announced
 

Is this where all new joiners can expect, or would other bases be possible?

Bases
 

Not sure BNA has been offered on a vacancy bid. If not, it would depend how many want it. There could be people based at TYS or CVG that might want BNA. GRR and PGD are very likely for new hires. There will be another base coming, but has not been publicly announced.

All vacancies for BNA were filled in September for a base opening in February 2020.

Of course they couldn't do it before Nashville got stupid expensive (thanks to the yanks from Chicago moving down).

Now the only affordable place to live is an hour outside of town... and the traffic now rivals that of LA/NY, etc

Nothing a little light rail and better bus system can't fix, ha ha ha. Just need to raise the property taxes to pay for it, should work out great. It might not be what the people of Nashville (and surrounding cities) want, but it's what they need.
