FAQs about flying to San Antonio

San Antonio climate

High temperatures and high humidity are the norm in San Antonio from late May through September. The autumn (September to November) and spring (March to April) seasons, however, are the best times to visit and explore the city. The days are warm and the nights are cool but soothing. Temperate weather during November and December make trips to San Antonio a pleasant experience.

Getting around San Antonio

San Antonio’s public transportation system is cheap and easy to use. The buses run regularly at reasonable rates, but you’ll need exact change. The VIA Metropolitan Transit Service also has streetcars that stop at tourist stops. You can tell where they’re going by the colour-coded signs listing their routes and destinations. Avoid driving around the city centre and save yourself the hassle of getting lost in all the one-way streets. You can find cabs easily at the airport or major hotels, but you’ll have to call ahead elsewhere.   

Local Airport

San Antonio International Airport (SAT) is around 8 miles (13 km) north of the centre of San Antonio.

San Antonio airport overview

San Antonio International Airport serves an average of eight million passengers per year and is located approximately 13km (8 miles) from downtown San Antonio, Texas. Flights to San Antonio International Airport come from a number of destinations, including Chicago, Houston, Atlanta, Detroit, Minneapolis, Newark, Memphis, New York, Denver, Washington DC, Salt Lake City, Phoenix, Charlotte, Baltimore, Denver, Orlando, Mexico City, Cancun, and Monterrey.

Recent building work has improved the handling capacity of the airport, as well as its accessibility. In 2010, Terminal 2 was closed and the newly built Terminal B was opened; the old terminal was then aptly named Terminal A and Terminal 2 was demolished in early 2011. A third terminal, Terminal C, is to be built by 2015. Furthermore, the construction of major roads – Interstate 410 and U.S. Highway 281 – has significantly improved transport flow and driving time to and from San Antonio International.

Although fairly limited in terms of shopping and dining options, amenities are sufficient and service is warm and friendly, much like the charming city of San Antonio.
