About San Antonio International Airport

Overview

San Antonio International Airport serves as a major commercial and cargo aviation hub in south-central Texas. Located at 29.533701, -98.469803, the airport sits at an elevation of 809 feet above mean sea level, providing strategic connectivity for the San Antonio metropolitan region. The airport supports diverse aviation operations with three substantial runways capable of handling large commercial aircraft.

Flying Conditions

San Antonio's airport environment experiences typical south Texas climate conditions with potential for significant thermal variations. The airport's elevation and geographic position can generate localized wind shifts and thermal turbulence, particularly during summer months. Pilots should anticipate potential crosswind challenges, especially on the shorter 13L/31R runway with its 5,519-foot asphalt surface.

Notable Features

The airport features three runways with substantial length: two concrete runways at 8,505 and 8,502 feet, and one asphalt runway at 5,519 feet. Its mid-latitude location means terrain surrounding the airport is generally flat with minimal elevation changes, providing relatively straightforward visual and instrument approach conditions. The three-runway configuration offers operational flexibility for different wind conditions and traffic volumes.

Approach Considerations

Runway 04/22 and 13R/31L offer the longest concrete surfaces, providing optimal landing options for larger commercial aircraft. Prevailing winds in the region typically favor east-west and northwest-southeast approach vectors. Pilots should carefully evaluate current wind conditions to select the most appropriate runway, considering crosswind components and available runway length.
