For decades, the San Antonio business community made the case that the nation’s seventh-largest city should have nonstop access to the airport closest to the nation’s capital, Ronald Reagan Washington National Airport (DCA). In March 2025, that goal became reality when American Airlines launched nonstop service between San Antonio International Airport (SAT) and DCA.
Now in its second year, the daily flight is making travel to Washington easier while strengthening connections between two cities where military, business, research and civic interests frequently intersect.
For travelers, the benefit is easy to see. San Antonians can board a flight at SAT and arrive just minutes from Capitol Hill and many of Washington’s major business and cultural destinations, without connecting through another city. This saves time and makes everything from a quick business trip to a family vacation easier.
But there was always more at stake with this route than convenience. Few communities outside Washington have ties to the federal government as significant as San Antonio. As Military City USA ®, San Antonio is home to one of the nation’s largest concentrations of military installations and defense personnel. The region’s growing cybersecurity, aerospace, bioscience, research and advanced manufacturing sectors also have important connections to federal agencies and programs.
For San Antonio companies and organizations, easier access to Washington can mean more opportunities to meet with federal officials, pursue partnerships, compete for contracts and build relationships. That matters especially in a city that is home to Joint Base San Antonio, one of the largest military missions in the country. And for companies considering investing or expanding here, air service is an important part of the infrastructure connecting them to customers and markets.
The flight also provides the Washington region with nonstop access to San Antonio, making it easier for business leaders, federal officials, military travelers and visitors to get here. Those visitors fill our hotel rooms, eat in local restaurants, attend conferences and events and spend money in our community.
The success of the DCA route also matters to the future of air service in San Antonio. New nonstop routes work when the community supports them. Every traveler who chooses to fly from SAT contributes to the passenger data airlines consider when deciding where to add or expand service. Strong performance on routes like SAT-DCA helps demonstrate that San Antonio can support more nonstop destinations.
SAT is preparing the infrastructure to support that growth, too. Construction is underway on a new 850,000 square-foot Terminal C, which is expected to open in 2028 with up to 18 domestic and international gates, expanded concessions, larger gate areas and a new central passenger screening area. The terminal is part of a broader investment designed to give our growing region the capacity and passenger experience it needs for decades to come. The investment is about more than a new building. It’s also about where San Antonio can go next.
The SAT-DCA route is an example of what better connectivity can do for our region. It makes travel easier, brings more visitors to San Antonio and strengthens connections to people and places that bolster our economy. As SAT continues working to bring more nonstop destinations to San Antonio, travelers have an important role to play. Using the routes we have today helps build the case for the routes San Antonio will land tomorrow.
