Glider and soaring operations occur approximately 17 miles northwest of the airport during VFR conditions.
Terminal gates A2, A6, A7, and A8 may be used only with prior permission; call airport operations.
Taxiway Z is closed to aircraft with a wingspan greater than 118 feet.
The inner ramp taxilane north of Terminals A and B is closed to aircraft with a wingspan greater than 135 feet.
Prior permission from airport operations is required for aircraft powering back from terminal gates.
Taxiways L and B are closed to aircraft with wingspans greater than 118 feet when exiting runway 31L.
The airport is restricted to aircraft with a wingspan greater than 171 feet; prior permission with 24-hour operations is required for authorization.
The following taxiways are not available for aircraft weighing 59,000 pounds or over: taxiway A, taxiway M, taxiway H northwest of taxiway Z, and taxiway E east of runway 04/22.

Aircraft taxiing on taxiway N southwest bound should look for the hold short line to runway 31R.
Aircraft on the east cargo ramp apron at the intersection of runway 04/22 and taxiway Delta are required to apply minimum thrust when crossing the runway to avoid damage from jet blast.
Noise sensitive areas exist on all sides of the airport. At pilots' discretion, climb as quickly and quietly as safely possible on departure, and use consideration when flying over populated areas by minimizing flight time and high power settings. Military aircraft departing and arriving will use minimum power settings consistent with aircraft flight manuals; afterburner takeoff is prohibited unless required for safety of flight. Engine run-ups are permitted between 0600 and 2300.
Numerous flocks of birds are in the vicinity of the airport.

Frequently asked questions
What is the longest runway at KSAT?
San Antonio International Airport's longest runway is 04/22, a concrete surface measuring 8,505 feet by 150 feet. Runway 13R/31L is nearly as long at 8,502 feet with the same 150-foot width, also concrete. A third runway, 13L/31R, is asphalt and shorter at 5,519 feet by 100 feet. That shorter runway carries an operational restriction limiting its use for certain scheduled and non-scheduled passenger carrying flights. Together the three runways give KSAT depth for a range of aircraft types operating into the field.
Are there restrictions on runway 13L/31R at San Antonio International?
Runway 13L/31R at San Antonio International Airport is not available for Part 121 or Part 380 operations when the flight is a scheduled passenger carrying operation with more than 9 passenger seats, or a non-scheduled passenger carrying operation with more than 30 passenger seats. This runway is also asphalt rather than concrete and is shorter and narrower than the field's other two runways, at 5,519 feet by 100 feet. A separate condition remark notes the runway has met its service life cycle and needs overhaul. Dispatchers should confirm current runway status before planning use of 13L/31R for larger passenger operations at KSAT.
How does San Antonio International handle U.S. Customs for general aviation?
San Antonio International Airport provides CBP inspection services onsite along with a USDA compliance agreement. International general aviation aircraft clear U.S. Customs at the north fixed base operator ramp on the east side, and pilots are instructed to call U.S. Customs upon arrival. Foreign military aircraft with a wingspan less than 100 feet must report to the GA ramp Federal Inspection Station for customs processing and contact airport management. C130 and C17 type aircraft must park on the west ramp to clear customs. These distinct procedures mean operators should confirm the correct ramp and process for their aircraft category before arrival at KSAT.
What wingspan limits apply to taxiways and the airfield at KSAT?
San Antonio International Airport applies several wingspan-based restrictions across its taxiway system. Taxiway Z is closed to aircraft with a wingspan greater than 118 feet, and taxiways L and B are closed to aircraft with wingspans greater than 118 feet when exiting runway 31L. The inner ramp taxilane north of Terminals A and B is closed to aircraft with a wingspan greater than 135 feet. At the airfield level, KSAT is restricted to aircraft with a wingspan greater than 171 feet only with prior permission from airport operations, available 24 hours. Operators of larger aircraft should plan taxi routing and authorization accordingly.
When is business aviation traffic busiest at San Antonio International?
Business aviation traffic at San Antonio International Airport shows a peak in April, with 4,248 operations recorded that month according to FAA TFMSC data. Other relatively active months include October at 3,624 operations and December at 3,473 operations. The quietest month is August, with 2,945 operations. KSAT's annual business aviation total for 2025 stands at 40,255 operations against 145,407 total annual operations at the field. This traffic is concentrated in certain months rather than spread evenly across the year, which is a factor worth noting for scheduling and slot planning.
