Not so fast
Seeing as this will pobably be your first job the rosters and destinations should be the last thing to worry about. If its not your first job then the fact that your looking to work in Indo as an experienced ATR driver means that your willing to take anything making the roster and destinations again irrelivant.
Seriously though its going to be a regional gig so the flying will be just that. Based out of Jakarta or Surabaya you will do the routes the others already do.
