Do a search about airnet and airnet bases. It doesn't matter if you have navajo time or baron time or caravan time. Everyone takes a checkride in the baron. Then bases are awarded. You may get a run that is baron only, or a run that might be baron / navajo. Or a run that is van only, or a run that is all three. If you get a run in birmingham, you might get a 310. It all depends what is open the time you pass your 135 pic check. Everything is senority based, so when a fl run opens up it goes to the highest person who bid on it. You are allowed to lateral and when you lateral you are allowed to get trained in 1 different aircraft, if I remember correctly, they have you sign another 1 yr agreement though. Hope this helps.
