American Airlines’ self-service check-in has got to be one of the greatest improvements made available to the flying public in recent history. I’d even put it above the “more legroom in coach” improvement and I’m a tall guy. Flying Public, why do you continue to wait in line at the checkout counter? You can check bags, sign up for stand-by, pick out seats, get boarding passes, and get a receipt all by simply tapping a few choices on the self-service kiosk. And because you continue to shun this incredible timesaver, I never have to wait in line–a benefit previously only known to the uppity First Class types. So, on second thought, please do not use self-service check-in. It sucks.
