IMHO.
Stay where you are, upgrade and get turbine PIC. Then you can apply for a National, or even a Major airline, and the pay is better down the road at those places.
But, if you feel you MUST move along, I agree with other posts, take the first job that comes your way, and if another one comes along, THEN worry about it.
I have a friend of mine that was so worried about what to do. Stay where he is or go to Continental? (He had an interview coming up) Well guess what, after all that worrying, he never got the job offer.
See if you get the job OFFERS, neverming the interviews, before you start worrying about things.
If it is not Skywest, do you work for GA?
