Overview & History
Stinson Municipal Airport (KSSF) sits about 7 miles south of downtown San Antonio and is owned and operated by the City of San Antonio. Established in 1915 by the pioneering Stinson aviation family, it is the second-oldest continuously operating general aviation airport in the United States, behind College Park, Maryland. Today it functions as the primary GA reliever for San Antonio International (KSAT), keeping private and corporate traffic clear of the commercial terminal.
Runway Capability
The primary runway measures 5,002 feet (10/28), extended and resurfaced in 2010 to attract business-jet traffic, with a 4,000 ft crosswind runway (14/32). This supports light jets through most super-midsize aircraft — Phenom 300, Citation XLS/CJ-series, Challenger 350, and Gulfstream G280 operate routinely. Heavy jets such as the Gulfstream G550/G650 or Global series can be feasible but require careful runway-analysis calculations for weight, temperature, and the field's 577 ft elevation; longer legs at high weight are better served from KSAT.
Charter Considerations
GateOne Stinson is the single on-field FBO and the point of contact for fuel, parking, and handling. Its location just south of the River Walk and downtown makes Stinson a fast, low-congestion option for trips into central San Antonio. Because the airport has a modest number of based business jets, charter aircraft are frequently repositioned in from nearby bases; The Jet Finder sources the closest available aircraft to limit positioning cost.
Safety & Planning
Stinson is a towered field (tower operational since 2019, frequency 118.2) during published hours, reverting to CTAF self-announce procedures overnight. Instrument arrivals rely on RNAV (GPS) and VOR approaches — there is no ILS — so equip and brief for GPS procedures in IMC. The 577 ft elevation keeps density-altitude effects modest, though hot South Texas afternoons should still be factored into takeoff performance for heavier aircraft.
Seasonal & Operational Factors
South Texas brings hot, humid summers and mild winters. The main operational variable is convective weather from spring through fall, with thunderstorms building rapidly in the afternoon. Morning departures consistently offer the most reliable, smoothest conditions. Haze and humidity can occasionally pull visibility toward IFR minimums without obvious cloud.
Regional Context
Within roughly 12 NM, San Antonio International (KSAT) handles full commercial and heavy-jet operations and provides U.S. Customs, which Stinson does not. Military fields including Lackland (KSKF) and Randolph (KRND) sit nearby but are restricted. For international arrivals or large-cabin missions that exceed Stinson's runway, KSAT is the natural alternate; for fast, downtown-adjacent GA access, Stinson is the preferred choice.
