Good news: it's small and easily accessible. Bad news: it's small and has limited facilities. Be sure to eat before you go through security if you want hot food.
If you have a 6am flight- they overbook that time slot, so get there 1.5 hours early or you will fall victim to the long TSA security line and miss your flight!
Oh TSA ... here's a tip for you. Your security procedures are horribly inefficient at every airport that you use random scan selection. Let us choose which lane to go through ourselves and less grope.
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.
