OAKLAND--one of the worst. Lots of low-cost flights and, unfortunately, low-class service. OAK is the armpit of Bay Area airports. I can recount three unpleasant experiences:

1) AWA flight pulls up. No gate agent to open the gangway entrance. Passengers just kept pushing the door open and setting off the security warning. "Stop! You are entering a secured area..." But, no airline employee or TSA showed up.

2) Twice I was waiting at the SWA terminal when I heard burping sounds on the overhead. Some employees thought it was funny to make gastric noises for the public enjoyment. Very unprofessional. Someone needs to tell them they're no longer in high school.

3) Recently, I was waiting in the security line when an airport manager cuts in front of everybody, saying loudly, "Excuse me, excuse me!" Plunks down her stuff on the x-ray belt. Gets into an argument with a businessman, whom she cut in front of. Ends up setting off the metal detector anyway. Granted there was a sign that stated flight crew and airport employees could step to the front of the line. However, she could have been more gracious. I spotted her five minutes later waiting for her food at the Pizza Hut.
