Mesa Airlines Pilot Development (MAPD) is based in Phoenix, Arizona and Farmington, New Mexico. I have experience with the Farmington system.
Its a great program, with many options for training depending on your current flying experience. You
CAN go from zero flight time to the right hand seat of a CRJ-900 in 250 hrs. !!There are no catches!! Mesa Airlines almost guarantees employment in one of their many aircraft types upon completing the course. I have many friends that have done the course and are currently flying for Mesa.

This is the fastest way into the airline business - just beware of Mesa Airlines and their managements treatment of pilots.

Good luck
