I am flying through LAX this Sunday the 24th and have a 3 hour layover. My flight lands at 1:40pm and then next leg leaves at 5pm. I have a local friend who's meeting at the airport so we can hang out for a bit before my next flight. My luggage will be checked through, so I don't have to deal with anything, just walk off the plane and hopefully into his car. My question is if anyone can guide me on how long I can safely be out of the airport, but still make my flight. I'm using my AA miles and flying first class, and not sure if there's a priority security line there. (I've been stuck in major security lines their in the past, so don't want to chance anything.) The sites I've checked say anywhere from 1 to 1 1/2 to 2 hours- but they all say it can depend on the day and time.
Any advice would be greatly appreciated, right now I'm leaning towards returning around 3:45.
