San Antonio International Airport began a $2.5 billion expansion in December 2025 to increase capacity and international reach. The ambitious master plan aims to help the facility achieve large hub status of 14 million annual passengers within five to seven years.
Why it matters
The project serves as a strategic effort to secure more transatlantic routes and handle long-term growth for the region. Airport leadership is also actively diversifying the carrier portfolio to fill gaps in service and maintain competitive capacity.
The expansion includes $1.7 billion for a new Terminal C and $300 million to overhaul existing facilities. Terminal C will feature 41,000 square feet of concessions and 29,000 square feet of lounge space upon its 2028 completion.
The players
San Antonio International Airport
This facility is the primary aviation hub for the city and is currently undergoing a significant physical transformation.
Jesus Saenz
He serves as the airport director who has overseen the strategic planning and long-term development goals for the airport since 2020.
Southwest Airlines
The carrier holds a 35% market share at the facility and was involved in litigation regarding gate assignments in 2024.
Spirit Airlines
This ultra low-cost carrier collapsed in the spring of 2026, creating a service gap at the airport.
The details
The airport is building 18 new gates to augment its current capacity of 27 standard gates and three ground load facility gates. These structural improvements are intended to stabilize operations after the collapse of Spirit Airlines in spring 2026 contributed to a recent decline in passenger volume.
Timeline
Jesus Saenz became the airport director in February 2020.
Terminal C construction officially began in December 2025.
Passenger volume reached 938,721 in June 2026.
Terminal C is scheduled for completion in 2028.
All terminal renovations are projected to conclude in 2032.
The Big Picture
The $2.5 billion investment aligns the facility with the Federal Aviation Administration's criteria for a large hub airport. By targeting 14 million annual passengers, the project seeks to move the airport into a new tier of regional importance.
Travelers should anticipate ongoing construction zones and potential shifts in gate locations through 2032. While the current traffic decline may lead to fewer flight options in the short term, the airport's recruitment of new carriers aims to expand route variety for local residents.
The takeaway
The terminal expansion represents a multi-year effort to modernize the local travel experience and attract major international carriers. Residents should monitor future airline announcements as the airport works to replace lost capacity and reach its hub growth goals.
