The car pickup location is not inside the airport. Despite providing my flight information, there was no one to pick me up upon arrival. I wandered around the airport and asked many people, including police officers, but no one knew where the America car rental office was. I had to call them, and only then did they come to pick me up. When picking up the car, I emphasized multiple times that I would return the car at 4 AM and asked if there would be any staff available. The office assured me that it would be open 24 hours and there would be staff present. However, when I went to return the car, the office was closed and there was no one around. I had to leave the car at the pickup location and throw the keys through a crack in the door. I later called them after landing in Los Angeles to confirm the return.
