AFI = Assistant Flight Instructor. This is the backup plan for most freshies after they graduate. Its basically another course which you will have to undergo in order for your to train cadets in a particular Flying Academy. If you can afford to pay for the course, you will not be bonded with the Academy for long, but If you need the Academy to sponsor you for the AFI course, you'll be bonded for at least 2 years minimum, correct me if I'm wrong.
After the bond, keep trying for Airlines, If no luck, then continue as an FI (Flight Instructor) and keep trying some more.
