Airnet is not the largest
Check out Ameriflight they are the largest non-scheduled 135 carrier. Airnet is good, too, but who would want to fly a Baron out of Columbus Ohio in the middle of the night and dead of winter!!! Well, I almost did, it really is a good company. Anyway, Ameriflight is hiring now into the venerable Piper Lance, upgrade to a Chieftain in a few (3-6) months, Turbine PIC probably around a year or so in the Metro or BE-99. Good luck.
