190 at Jb is the same, doesn't go further west than Texas .. Hasn't for years . On the 190 you ll do multiple leg days all over the east cost and a bit of island flying. Fll-STI and SJU flying etc.
The 320 does a majority of our flying here , that being said I try to do mostly up and down the east coast cause that were my seniority can get the most credit out of a trip. The 320 does all the west coast stuff , which tends to go junior cause it's less efficient hence earning less money for the amount of days your working. It seems that once your a line holder on the 190 you ll find your self with a commuter friendly schedule much quicker than you will with the airbus . The bus has good trips but unless your senior you won't find good credit trips worth much more than 23 hour 4 day that is commuter friendly. (Garbage)

Honestly the 190 does do what most would call regional type flying , I did nearly the same exact stuff when i was flying delta connection.
