Very nice. Basically 9W checkin agents also go around the terminal with a handheld scanner and a tiny boarding pass printer strapped to their belt. If you have an etix and dont need to check any bags you can just checkin with one of these guys. Makes a nice, personalized addition to their kiosk checkins if you want to beat the checkin queues.
