We left Chicago -O'Hare (ORD) for Las Vegas (LAS) on United Flight #1495. The aircraft was a Boeing 737-800. Though we left the gate about five minutes late, we were delayed on take-off about nine minutes for an unknown reason. The flight, itself, was nice, smooth and uneventful. We landed about ten minutes late, but we actually made it to the gate a few minutes earlier, so we were on our way to hit the "one-armed bandits". From the skycaps at the curbside counter who checked us in and took our luggage, all the way through our exiting the plane, the staff was very efficient and friendly. Can you really ask for a lot more than that?
