So I'm a young (19y) pilot with about 320TT and 60HRS Multi TT.

I fly now and then with a 135-operator without pay just to build up the hours...but much rather fly with a company that would pay also :-)
Anyone know what would be the best course of action to take at this stage?
Or if regionals, cargo operators,etc hire with this amount of TT and my AGE (19)...
Any help welcome :-)

I'd worry more about working getting that sheepskin then trying to get on with a regional, etc.

Sorry but someone has to say it...

320 hours and you want to fly people, not gonna happen... nor should it. Unless you've gained that experience in the military, you have no business in the cockpit of a transport category aircraft.

Do what the rest of us did, go be a flight instructor. You'll be a better, more respected pilot for having done so.

How do you fly for a 135 operation with 320 hours? I guess you are sitting right seat, but then, how are you logging it?

You need a lot more total time, or your CFI ratings, to get paid to fly.

I agree 100%! Go to school! It only gets harder the longer you wait, trust me I know. I wish I had gone to college right out of high school, which I'm guessing is basically where your at. You'll need the degree sooner or later, and I wouldn't wast my time on any aviation degree either, diversify yourself.

whenever I can sit left seat w/o pax. Thats one way of bldng hrs.

Yeah I know. And im not wasting time on any aviation degree either.. I'm actually majoring in Computer Programing right now.

But you don't have 135 times. How can you fly a 135 flight? Even for VFR you need 500 hours.

you need only CPL and IR if required...the minimum time is set by the operator not by FAR.
