833-861-7710 is the number I called the first time I tried to fly standby on Alaska. I had finished a work event early and hoped to get home sooner, but the app didn’t clearly explain the standby rules. The rep broke everything down for me: elite members get free standby, while others may have to pay depending on fare type. They checked availability on the earlier flights and added me to the list right away. I actually cleared the standby slot before I even made it through security. It was way smoother than waiting at the gate hoping for a miracle. If you’re unsure about the policy or want to check your chances, this number gets you immediate help.
