Port San Antonio's Kelly Field (SKF) has a 11,500 foot (3,505 meter) runway which can handle all heavy lift aircraft. Immediately adjacent to the runway is 575 acres (232.7 hectares) of mixed use airport property. The entire airport, along with the adjacent property is with the Port's General Purpose Foreign-Trade zone #80-10.
The Port's airfield has sufficient space available on the ramp areas and terminals for quick re-fueling and efficient turnarounds.
The airfield is operated under a joint use agreement with Lackland Air Force Base. Both entities are co-located on either side of the runway, which affords the airport exceptional security.
