The terminals are arranged in a circular format that is referred to as The Terminal Loop. Terminals 1, 2, and 3 serve primarily domestic flights, while the International Terminal serves (you guessed it!)
Terminal 3 opened on June 27, 2012. The project was announced in January 2001 as a way to accommodate rapid growth in passenger traffic, including international traffic.
You will need to reclear TSA security once you arrive in your departure terminal. For international arriving passengers, you must claim all checked bags at Customs and recheck with your departing airline, even if the bags are checked to your final destination!
