Don't fear filing if you're out of state. 

Since I always wait until after the 1st of the year to do my annual 3 week or so winter escape, I too have filed from places like Hawaii and California. When I came to the in-state / out-of-state question, I clearly indicated I was out of state, clarified when I left Alaska and when I was going to return. Plus I had Alaska Airlines mileage plan activity documentation to prove it if the Revenue Dept ever had questions. I never, ever had a problem or a delay in receiving my PFD
