I normally commute on Alaska, SWA, or United. Getting up there I usually have lots of options out of Denver and through Seattle, including United nonstop to Anchorage. Unfortunately, the number of flights out of Anchorage at the time I am looking to leave seems to have shrunk or are more heavily booked. My last two commutes home I listed on 3-4 flights before actually getting a seat. That said, I’ve only had to commute once a month, so not exactly a deal breaker.
