American airlines now let's you have a mobile boarding pass, no more printing paper, check in and use your iphone as your boarding pass!!! Genius! Why didn't they think of this sooner?
Food options in the terminal are pretty sparse. Eat before you get to the airport! Also while terminal 2 is under construction the security lines can get pretty long so get here early.
Gates 1 and 2 (and 1a?) are not near 3-10. So if you arrive at 3-10, you have to go through another security checkpoint when connecting. Even though you just got off a flight. -_- Worst. Setup. Ever.
Friendly staff throughout, but extremely slow security lines. Not sure why, but SAN typically has the slowest security lines of any airport I frequent.
Do not get coffee for anywhere but Starbucks. Not a Starbucks fan, but I ordered coffee from one of the "restaurants" took a sip, paid for it & left it on the table. It was undrinkable.
