San Marcos International Airport (MCS)

San Marcos International Airport is a planned international airport to be located southeast of San Marcos, Texas, and is roughly equidistant from San Antonio and Austin. It is a few miles to the south of I-35 just to the south of San Marcos. It is adjacent to a local river and has three runways, two running southwest-northeast and one running northwest-southeast. It primarily serves San Antonio and Austin and caters to long haul flights. It is also seen as a viable alternative by low cost carriers to serve two towns instead of one. It faces competition from Austin Bergstrom Airport and San Antonio International Airport. It will take about 10 years to construct and will cost just over 1 billion dollars. It is planned to have one terminal with a maximum of 40 gates. It is a hub for Hite Virgin Airlines and is a base for maintenance for Hite Airlines.

The airport is planned to have 40 gates in one terminal and is planned to have support facilities around the airport. The terminal consists of a single building and is also connected to the control tower. It is also a popular place for private and charter aircraft to land because of its location between the two cities. Austin and San Antonio will have bus access and taxi services from their respective sides.

Planned international destinations include: Frankfurt, London, Cancun, Toronto, Calgary, and Vancouver, among other cities.

Planned popular domestic destinations include: Chicago, Dallas, Atlanta, New York, Denver, Houston, Phoenix, Los Angeles, Las Vegas, and C-City
