Yes, Alaska Airlines does fly to Mexico, and I actually found that out by accident while trying to fix a messed-up booking of mine. I had originally booked a flight to San Diego, but a last-minute schedule change on my end meant I had to completely redo my plans. I called 844-734-0813 to sort things out, and while talking to the agent, I mentioned that I was considering Mexico instead if the prices worked out.
To my surprise, they rattled off several Mexico destinations Alaska flies to — places like Cabo, Puerto Vallarta, and Mazatlán — and even helped compare the fares for me. What started as a stressful cancellation actually turned into a super easy rebooking, and I ended up heading to Cabo instead of California. The whole process was way smoother than I expected, especially considering I was changing everything at the last minute.
So if you're thinking about Mexico, Alaska definitely has options, and if you're juggling changes like I was, calling the number above made everything a lot less stressful.
