This place is a hot mess. They have 2 gates separate from the rest, where you have to leave and re enter. Which btw, security isn't the greatest, they didn't know how to work the machines :-/
If you are connecting between Terminal 1 and Terminal 2, the craptastic design of SAN requires you to leave security, catch a bus to the other terminal, then go through security again. Horrible!
If you like being able to eat or drink something before your flight don't fly Southwest. Slim pickings coupled with long waits equals a fistful of suck.
Guy at security gave me some interesting facts about the full body scan. Only women look at women, they are in a booth and aren't allowed out until all they scanned have left the area.
