Southwest has been testing CS2 at airports in Amarillo, Midland and Tulsa, Okla. It will be rolled out to Love Field at the end of the month and expanded to the rest of Southwest's system by mid-November.
Very nice to hear it is being beta tested in real service situations. I know of too many companies who release software updates or new systems and just do a cursory beta test and then launch it live on their entire system. Remember US upgrading their systems when they merged the HP and US systems. Wasn't it all check-in kiosks were down for the better part of a weekend?
