San Marcos Regional Airport (KHYI) is a medium airport in San Marcos, TX. It sits in North America.
San Marcos Regional Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 6,330-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.
The longest runway measures 6,330 ft (1,929 m), a midsize and super-midsize-class field. Representative aircraft that operate comfortably here include the Citation Longitude, Challenger 350, and Gulfstream G280. In practice this comfortable for most midsize and super-mid charter equipment.
San Marcos Regional Airport sits near sea level at 597 ft.
Local operations run on America/Chicago. Without scheduled airline traffic, the field tends to be quieter and more flexible for charter and corporate operations — a useful characteristic for early morning, late night, or short-notice flights that would be impractical at a hub.
SkyAccess currently tracks 6 departing and 7 arriving private-jet legs at KHYI across the next six months of operator inventory. 3 charter operators have run trips through this field in our recent inventory window.
Regional fields like KHYI are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.
