How many MX bases are we looking to end up with? We already have 4.

To the prior, I'm going to go ahead and say absolutely no way XNA becomes a CREW base. The company is going to be in trouble staffing wise. XNA not only doesn't help recruiting efforts, it may harm them if a new hire knows they are going to be stuck in Arkansas for 6 months after being hired.

The next base will be a hub. I still haven't seen this rumored "Chicago flying" but I have seen a crap ton of LGA flying. I'd bet on one of those.
