Distance between Austin and San Antonio



Driving non-stop from Austin to San Antonio

How far is San Antonio from Austin? Here's the quick answer if you drive this relatively short distance without making any stops.

Nonstop drive: 79 miles or 127 km

Driving time: 1 hour, 21 minutes

Even though you can drive this distance straight through, it might be more interesting to stop along the way. You can scroll down to calculate how many hours it would take if you drive with stops.




Flying non-stop from Austin to San Antonio

Now let's assume you have a private jet and you can fly in the fastest possible straight line between Austin, Texas and San Antonio, Texas. Because of the curvature of the Earth, the shortest distance is actually the "great circle" distance, or "as the crow flies" which is calculated using an iterative Vincenty formula.

Flight distance: 74 miles or 118 km

Flight time: 39 minutes

The straight line flight distance is 5 miles less than driving on roads, which means the driving distance is roughly 1.1x of the flight distance.

Your plane flies much faster than a car, so the flight time is about 1/2th of the time it would take to drive.

This is a relatively short flight in a private plane, but you might be planning to book a commercial flight. In that case, your travel time would really need to include how many minutes to get to your local airport, wait for security, board and taxi on the runway, land at the other airport, and get to your destination. Scroll down to see a more realistic calculation that takes into account all these factors to get a more accurate estimate of your actual flight time.

Austin to San Antonio airports and flights

In the quick calculation above, we assumed you had a private plane and just wanted to know the time in the air from city to city. But for most of us, we're going to be flying on a commercial airline (whether it's first class or coach). So that means we really need to account for all the extra travel time getting to the airport, waiting for our flight, and making it to the destination.

To give you a better estimate of real-life travel, we've put together a flight itinerary with actual airports. Eventually you'll be able to customize this plan, choosing your own airports and flights. But for now, here's an example we've selected to give you an idea of how traveling might work between airports.

Departure airport: Austin-Bergstrom International Airport (AUS)

Arrival airport: San Antonio International Airport (SAT)

With the airports selected, we can estimate the travel time to and from the airport, based on how far the airport is from downtown.

Getting to the airport: 20 minutes

Getting to your destination: 22 minutes

Now finally, let's look at an actual flight from AUS connecting through IAH and arriving at SAT flying on United Airlines. We can figure out how long it would take to fly including take-off and landing, time to taxi on the runways, and an average layover time of about 2 hours.

Initial flight time: 57 minutes

Connecting airport: George Bush Intercontinental Airport (IAH)

Connection flight time: 59 minutes

So now we can finally get an idea of the total travel time from Austin to San Antonio including time spent getting to and from the airports, roughly 2 hours at the departure airport for TSA security lines and waiting at the gate, plus the connecting flight with a 2-hour layover.

Total travel time: 7 hours
