San Antonio International Airport is hitting a chilly stretch in the middle of winter, with fewer seats in the sky and softer passenger counts after two years of record-setting growth. The slowdown has city leaders and local businesses watching the monthly numbers like hawks while a major terminal expansion keeps rolling forward in the background. Airport officials say they are working to steady flight options even as demand cools, according to San Antonio Business Journal.
Fresh local data shows SAT handled nearly 725,000 passengers in January, while scheduled airline seat capacity at the airport slipped about 8%, as reported by the San Antonio Business Journal. According to that reporting, airport leaders are actively courting carriers and hunting for extra frequency on existing routes to keep service from sagging further.
First annual dip since pandemic rebound
On a yearly basis, SAT moved roughly 10.7 million passengers in 2025, a 3.2% drop from 2024, which ended a two-year run of record highs, according to Axios San Antonio. Axios also reports that air cargo went the other direction, climbing about 15.7% last year. Airport staff pointed to economic uncertainty and last fall’s federal government shutdown as factors that took some wind out of leisure and business travel demand.
Terminal expansion keeps moving despite slower traffic
Even with passenger traffic easing off, the City of San Antonio is pushing ahead with a multibillion-dollar Terminal Development Program that will add gates and update passenger processing. Federal environmental approvals and planning documents are posted on the airport’s statistics and financial portal. According to the airport’s published planning pages, the buildout is meant to boost SAT’s long-term competitiveness and capacity, even if month-to-month traffic looks bumpy for now (San Antonio Airport statistics).
What local leaders are betting on next
City and airport officials say that snagging a few new routes or restoring flight frequencies could help offset the winter slump. One bright spot on the calendar is Air Canada’s seasonal Toronto service, which is set to start in May, and the city is still pitching other airlines on additional nonstop options, per reporting from San Antonio Business Journal. The thinking is straightforward: if airlines eventually put more seats back into the market, the new terminal will give SAT room to grow when demand rebounds.
For now, the clearest signs of how this plays out will come in the monthly operational reports that track seats, passengers and cargo, the same numbers airlines and local officials pore over when deciding where to add or trim service. San Antonio Airport statistics publishes those figures each month.
