A lot of those charter companies will pay to positive space you in Econ I believe so commuting isn't an issue. Do you have your ATP written done? If not, you need to look in to the ATP CTP courses, which are required. That is where a regional would be nice since most pay for that now. I'm sure there are GI bill ways to do it too, but I don't know for sure. As for the ATP itself, assuming you are using GI bill, look into higher power and get a 737 type. Otherwise, that's another benefit of a regional. Another type and free (kind of) ATP rating.
