Reference data

Estimated traffic profile

The figures below are projected from the FAA's airport-class definitions and the Bureau of Transportation Statistics' published baseline ranges for each class. They are intended as orientation, not as a substitute for the live BTS T-100 segment data, which is updated quarterly.

Runways & airfield

The airfield carries an estimated 2 runways, with the longest runway running approximately 7,900 feet. A runway of this length supports narrow-body mainline jets such as the 737-800, A320 family and 757 at typical operating weights, but is short of what wide-body international service usually requires. Pavement type, lighting, instrument-approach minima, and any displaced thresholds are all published in the FAA's NASR record for the airport, pilots should consult the live AIP and current charts rather than relying on summary figures here.

Parking at KHYI

Parking at San Marcos Regional Airport spans the standard tiers you would expect at a medium hub airport. Short-term and hourly rates typically run between $3–$5 per hour, depending on whether you park in the garage closest to the terminal or in a satellite lot. Daily economy parking generally runs $10–$16 per day, with off-airport private lots usually undercutting the long-term garage by a few dollars per day in exchange for a short shuttle ride. A free cell-phone waiting lot is available for drivers picking up arriving passengers, sparing them the curbside-loitering ticket that has become standard at most US airports. Always cross-check rates on the airport's own website before you travel, parking pricing is one of the most volatile data points at any airport.

Ground transport & rental cars

Ground transport options at San Marcos Regional Airport reflect the airport's role in the local ecosystem. Rental-car desks for the major brands (Hertz, Enterprise, Avis/Budget, National, Alamo) are available either inside the terminal or at a consolidated rental facility a short shuttle ride away, follow signage for "Rental Car Center" on arrival. Public transit reaches the airport via local bus or rail, which is usually the most economical way into the city center for travelers without a lot of luggage.

Ride-share pickup and drop-off zones at US airports are increasingly being moved to dedicated lots away from the main curb, check signage on arrival rather than relying on memory from past visits. Pickup wait times at peak hours can be substantially longer than the app's initial estimate, especially when bad weather concentrates demand. Pro tip: if you have a tight outbound connection, a pre-booked private car often beats ride-share on reliability for early-morning and late-night flights.

TSA security & checkpoint expectations

Average TSA security wait times at San Marcos Regional Airport typically range from 5–14 minutes off-peak, climbing to 23 minutes or more during the early-morning and late-Sunday rushes. TSA PreCheck lanes, where available, usually clear in under five minutes regardless of class. Travelers without PreCheck can typically save the most time by arriving outside the 5–8 a.m. and 4–7 p.m. windows when business traffic concentrates at most US airports. The TSA publishes official screening guidance for current rules on liquids, electronics and prohibited items.

Traveler tips for San Marcos Regional Airport

If you have a connecting itinerary through San Marcos Regional Airport, build in a buffer that matches the airport's class. Medium hubs typically run a single linear terminal and a handful of concourses; 45 minutes is a reasonable minimum domestic connection for most carriers here.

• Book the right airport. Travelers comparing flight options should look beyond the obvious nearby large hub, a closer medium or regional airport like San Marcos Regional Airport can shave an hour off the total door-to-door time even when its ticket price is slightly higher.
• Read the operating carrier. When a flight is sold under a major carrier's code but flown by a regional partner, the operating carrier is normally disclosed on the booking page; this distinction matters for elite-status benefits and irregular-operations rebooking.
• Watch the weather. Weather delays at this airport propagate to and from the connecting hubs in the carrier's network, track the inbound aircraft, not just your departure board.
• Confirm baggage rules. Some regional aircraft (especially turboprops and small regional jets) gate-check carry-on bags as a matter of routine because of overhead-bin capacity. Pack medications, electronics, and valuables in the bag you intend to keep on your person.
