Seattle is a tough place to commute from unless you live in base. Also, consider companies with commuter clause. SkyWest, despite all CA bases, doesn't have the commuting policy. I have never got a chance to work there and see how anal screw scheduling is but in the words of one ground instructor 'you have to be there'.
I have an interview coming up with Republic and i will have to turn down the job if they offer me something that i cannot even commute. (SDF, CMH, etc).
I was turned down by Horizon last year and have no intentions of applying this year.
Mesaba turned me down at the application level which sucked because MSP/DTW commute wouldn't be bad. (Long commute is fine because you can catch some ZZs).

In my case I cannot move outside of Seattle for two major reasons:
- I own a local business.
- I have been waiting for my citizenship for a year and moving resets the whole process. Given the wait time of 2-3 years now, i am staying put in Seattle.
