SACRAMENTO (Azat TV) – Sacramento International Airport (SMF) has experienced remarkable growth over the past decade, significantly driven by a surge in passenger traffic to Las Vegas. However, recent data from 2025 reveals a notable dip in this key route, signaling a shift in travel patterns even as SMF continues its overall expansion as California’s fastest-growing major airport.
New county data shows that SMF averaged 38,000 daily passengers in 2025, a jump of nearly 12,000 daily passengers from a decade earlier. This growth rate surpasses all other major California airports, nearly doubling that of the second-fastest growing, San Diego. Last year, SMF handled a record 13.4 million domestic passengers, up from 9.4 million in 2015, elevating its national ranking for domestic travel from 42nd to 36th busiest.
Sacramento’s Decade-Long Growth Fueled by Vegas
For the past decade, Las Vegas has been the single biggest growth destination for passengers departing from Sacramento International Airport. During the 12 months ending in November 2025, approximately 608,000 passengers boarded flights to Las Vegas, effectively doubling the number recorded in 2015. Stephen Clark, deputy director of commercial development for the Sacramento County Department of Airports, highlighted Las Vegas’s enduring appeal for “quick weekend travel, major events and conventions, and strong visiting-friends-and-relatives traffic,” noting its status as a “highly competitive, low-fare market.”
Southwest Airlines, the dominant carrier at SMF, significantly contributes to this traffic by routing many passengers through Las Vegas’s Harry Reid International Airport (LAS). Mark Davis, who manages the airport department’s air service development, explained that Southwest utilizes LAS as a connecting point with as many as 260 flights a day, enabling connections to cities without direct flights from SMF.
The Recent Dip in Sacramento-Vegas Flights
Despite the long-term growth, passenger traffic from SMF to Las Vegas experienced a dip of about 90,000 passengers last year. This decline is part of a broader nationwide trend of fewer vacations to Las Vegas. Reflecting this shift, Spirit Airlines and Delta Airlines recently discontinued their direct service from SMF to Las Vegas. While Southwest continues to leverage Las Vegas as a critical hub, the reduction in direct flights from other carriers indicates an evolving market dynamic.
Broader Airport Dynamics and Future Outlook
Beyond Las Vegas, SMF has seen significant growth in other destinations. San Diego, Denver, and Hawaii have also added substantial passenger numbers over the last decade, with Mexico routes to Guadalajara and Cabo experiencing fast international growth. Airport officials attribute some of SMF’s overall passenger influx to Bay Area residents increasingly choosing SMF over busier San Francisco International Airport (SFO) due to easier access and more competitive parking rates. Randy Sieg, a frequent traveler, specifically praised SMF’s convenience and $12 daily economy parking, a stark contrast to SFO’s $27.
Looking ahead, SMF officials project steady overall demand growth of roughly 2–3% per year, anticipating 20 million annual passengers by 2038. To accommodate this expansion, a new parking garage is set to open soon, with six additional gates at Terminal B nearing completion. Further infrastructure developments, including more gates at Terminal A or a potential new Terminal C, are also being considered.
The recent dip in Sacramento-Las Vegas flight numbers, despite a decade of robust growth, underscores how specific market segments can fluctuate even within an overall booming airport environment, prompting airlines to optimize networks and highlighting SMF’s need for diversified route development.
