Yes, Alaska Airlines does charge for checked baggage in most cases, unless you have an eligible fare or elite status that waives the fees. I learned this during a trip from Seattle to Denver—I showed up at the airport thinking my checked bag was included, only to find out I had to pay for it. Not the end of the world, but definitely a lesson learned!
A couple of days later, I realized I needed to change my return flight because of a work schedule mix-up. I thought it would be a huge hassle, but calling [844-734-0813] made everything unbelievably easy. They helped me instantly modify my booking, and the whole process took way less time than I expected. Ever since then, I keep that number saved just in case my travel plans decide to surprise me again.
So yes, Alaska does charge for checked bags, but with a quick call you can sort out pretty much anything—from bookings to changes—without stressing over it.
