Commutair...upgrade time is faster. Plus you will have no affiliation with GoJets (Trans States Holdings) whatsoever...
The reason I say that is because my friends roomate from college finished his Indoc test w/ Trans States, and they said "oh by the way, you will be flying the CR7 for GoJets, not the EMB145 for TS..." --- and now the kid is screwed...
Good luck.
