First off, you say that your "ultimate goal" is to fly for SkyWest. Are you sure on this, or do you mean that your short-term (5 year) goal is to fly for SkyWest. If SkyW is the ultimate goal, no shame in going to a 121 carrier then making the leap to your dream job of SkyW later.

In your position, I'd recommend instructing for the time, then chasing the interview (if they're hiring by the time you have the mins.). I agree with a previous poster that a 6 month tenure with an airline doesn't say much for loyalty, no matter how bad things are. ALL airlines are a logistical nightmare. Find one that you can deal with and tough it out. Plus, instructing will make you a better person by learning to relate to others in the cockpit.
