I can definitely share from my own experience — yes, Alaska Airlines does include a carry-on with most of their fares. I learned this the hard way during a last-minute business trip to Seattle. I was juggling meetings, trying to rebook my flight after a schedule change, and the last thing I needed was baggage confusion. I had booked a regular Main fare, and thankfully my small roller bag and backpack were both allowed without any extra fees.
What really saved me during that hectic trip was when I had to adjust the return flight. Instead of fighting through the website, I called 844-734-0813, and honestly it was the fastest way to get the change processed. The agent confirmed my fare still included the carry-on, even after modifying the booking.
So yes — Alaska does include a carry-on, and if you ever need to sort out booking questions or make last-minute changes, that number is a lifesaver.
