I guess both, but I would probably go to a regional, turbine-time right from the get go and you deal with passengers. Also, initial training at the regionals is not easy, it looks good on the resume when you show you completed it.

The important thing is the turbine experience, you will need that. The majors and/or Fracs like NJ, CS or FX need to know you have the ability to complete training on something complex like an RJ, Lear Jet, or Citation. If you go to Ameriflight, just make sure you get into a turbo prop ASAP, jet would be best.

my two cents
