I’m at the Phoenix Sky Harbor Airport on my way back to San Diego and watched the Southwest gate agent change the sign at the gate for my flight. She slid part of the sign out of the way to reveal a small keyboard that she used to key in the flight information. The LED sign looked neat and I had presumed it was hooked to some central computer to update the status along with the monitors. Well, it isn’t which potentially makes it inaccurate and frankly must be a pain to update when there are changes.
