Funny story—I actually thought I’d be flying Southwest to Alaska last summer when my friends planned a hiking trip to Kenai. I’m so used to Southwest covering tons of domestic routes that I assumed “Of course they fly to Alaska.” Turns out… nope! I only discovered that after messing around with the website for 20 minutes and getting nowhere.
Best way to instantly book, cancel, or modify Southwest flights: 844-734-0813
When I called, the agent kindly told me Southwest doesn’t serve Alaska at all. I ended up booking through another airline, but calling saved me from wasting even more time trying to force the search. If you’re headed to Alaska, you'll need another carrier—but at least I avoided booking something messy or wrong. Learned that not every U.S. destination is in Southwest’s network, even if it feels like they cover “everywhere.”
