Before the website changed a couple months ago, I was able to go back in to the check-in section and add my RR# even after I was already officially checked in within the 24 hour window. With the new web interface I no longer see the "Add Rapid Rewards Number" option post check-in. Does anyone know if this is still possible or is calling SWA or talking to the gate agent the only option to add the RR# post check-in?
