There aren't any signs outside security to tell you which gate your American flight will be using. Call AA to get gate info vs. having to wait in line to ask an agent.
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?
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.
