Once you have gone through the security gate, follow the road al the way to the last stop sign. At stop sign, turn right, go by the pedestrian walkway, then make an immediate left into the South Tower entrance. From here you may elect to go to the upper "open" deck or make an immediate right and enter the lower parking deck area. For unloading and loading, the Lower deck is where you will find luggage carts to assist you for load in and load out.
