Southern California’s Tourism Boom: Ontario International Airport Expands Global Reach with New Routes
Southern California is seeing a remarkable increase in tourism, and much of this growth can be traced to the rapid expansion of Ontario International Airport (ONT). With new nonstop flights to Taiwan, Mexico, and major U.S. cities, ONT is transforming travel options for residents and visitors alike. This article provides a detailed look at the latest developments, the impact on the region, and what travelers need to know about these changes.
Ontario International Airport: A New Era of Connectivity
Ontario International Airport, located in the heart of Southern California’s Inland Empire, has emerged as a major player in the region’s travel landscape. Since gaining local control in 2016, ONT has experienced a 67% increase in passenger traffic, reaching over 7 million travelers in 2024—a 27% jump from pre-pandemic levels in 2019. This surge is not just a number; it represents new opportunities for tourism, business, and cultural exchange across the region.
Why Is ONT Growing So Fast?
Several factors contribute to ONT’s rapid growth:
- Strategic Location: ONT serves the Inland Empire, one of the fastest-growing areas in California, and offers a convenient alternative to the often-congested Los Angeles International Airport (LAX).
- Local Control: Since the transfer from Los Angeles city authorities in 2016, the Ontario International Airport Authority (OIAA) has focused on targeted investments and route development.
- Airline Confidence: Major carriers like United Airlines and international newcomers such as STARLUX Airlines are betting on ONT’s potential, adding new routes and increasing seat capacity.
Breaking News: New Routes and Expanded Services
The summer of 2025 marks a turning point for ONT, with several high-profile route launches and service enhancements.
United Airlines Launches Daily Nonstop to Chicago O’Hare
On May 22, 2025, United Airlines began daily nonstop flights between Ontario International Airport and Chicago O’Hare International Airport (ORD). This new service, operated with a Boeing 737-800 featuring 166 seats across First, Economy Plus, and Economy classes, departs ONT at 7 a.m. Pacific Time and returns from ORD at 7:55 p.m. Central Time.
Why does this matter?
Chicago is ONT’s 27th nonstop destination, providing travelers with direct access to one of the nation’s largest transportation hubs. This route opens up seamless connections to the Midwest, East Coast, and international destinations via United’s global network.
STARLUX Airlines Connects ONT to Taipei, Taiwan
Starting June 2, 2025, STARLUX Airlines will operate four weekly nonstop flights between ONT and Taipei Taoyuan International Airport (TPE). Flights leave ONT at 11:10 p.m. and arrive in Taipei early morning two days later, due to the time difference. The return flight lands at ONT’s International Arrivals Terminal.
The route uses the Airbus A350-900, offering 306 seats across First, Business, Premium Economy, and Economy classes. This is a significant development for Southern California’s large Taiwanese and Chinese communities, as well as for business travelers and tourists seeking direct access to Asia.
Volaris Adds Service to Guadalajara, Mexico
Volaris, a leading Mexican airline, will launch new flights from ONT to Guadalajara (GDL) in summer 2025. This addition strengthens ONT’s role as a gateway for travelers with family, business, or tourism ties to Mexico.
Summer 2025 Passenger Forecast
ONT expects to handle 2.22 million passengers during the summer travel season (May 23 to September 1, 2025), a 1.7% increase over 2024. Monthly projections are:
- June: 664,000 passengers
- July: 672,000 passengers
- August: 671,000 passengers
With 2.85 million seats available (a 3.4% increase from 2024) and a projected seat occupancy rate of 77.8%, ONT is preparing for its busiest summer ever.
What This Means for Southern California
Boosting Tourism and the Local Economy
According to Atif Elkadi, CEO of the Ontario International Airport Authority, ONT’s growth is a major driver for the Inland Empire’s tourism economy. The region generates nearly half a billion dollars in tax revenue and supports over 180,000 jobs. Expanded air service means more visitors spending money in local hotels, restaurants, and attractions.
Tourism experts agree that better air connectivity directly increases visitor spending. With new international and domestic routes, ONT is helping Southern California attract tourists from around the world, supporting businesses and creating jobs.
Making Southern California More Accessible
The addition of nonstop flights to cities like Chicago, Taipei, and Guadalajara makes it easier for travelers to reach Southern California without the hassle of connecting flights or long drives from other airports. This is especially important for:
- International tourists seeking direct access to the region’s beaches, theme parks, and cultural sites
- Business travelers who value time savings and convenience
- Families visiting relatives or attending special events
Relieving Pressure on LAX
ONT’s expansion helps reduce congestion at Los Angeles International Airport, which is often crowded and challenging to navigate. By offering more options in the Inland Empire, ONT provides a smoother, less stressful travel experience.
How the New Routes Work: Step-by-Step for Travelers
Travelers using ONT’s new routes can expect a streamlined process:
- Booking: Reserve nonstop flights to Chicago, Taipei, Guadalajara, and other destinations directly through airline websites—United Airlines, STARLUX Airlines, or Volaris.
- Check-in and Security: Arrive early, especially for international flights, to allow time for check-in, security screening, and customs procedures.
- Real ID Compliance: Starting May 7, 2025, all domestic travelers must present a Real ID-compliant driver’s license or another acceptable form of identification at TSA checkpoints. For more details, visit the U.S. Department of Homeland Security’s Real ID page.
- Boarding: Proceed to the designated terminal (for example, STARLUX departs from Terminal 4).
- Arrival and Connections: Upon arrival, connect to other flights (such as through Chicago O’Hare) or clear customs and immigration for international arrivals.
- Ground Transportation: ONT offers curbside rideshare pickup, parking, and shuttle services to local destinations.
Policy Changes and Practical Implications
Real ID Enforcement
The Real ID Act requires all domestic air travelers to present compliant identification starting May 7, 2025. ONT officials are urging travelers to check their IDs and update them if necessary to avoid travel disruptions. For more information and to check if your ID is compliant, visit the official DHS Real ID page.
Expanded Customs and Immigration Services
With international passenger numbers reaching a record 438,896 in 2024 (a 5.1% increase), ONT is expanding customs and immigration facilities. This includes more staff, improved processing areas, and enhanced amenities like Aspire Lounges and duty-free shopping. These upgrades aim to provide a world-class experience for international arrivals and departures.
Airline Competition and Consumer Benefits
As more airlines add routes at ONT, travelers benefit from:
- More choices in destinations and flight times
- Competitive pricing due to increased competition
- Improved service quality as airlines vie for customer loyalty
According to analysis by VisaVerge.com, this competition can lead to better deals and more flexible travel options for both leisure and business travelers.
Voices from the Airport and Industry
Alan D. Wapner, President of the OIAA Board of Airport Commissioners, highlighted the significance of ONT’s new routes:
“The addition of Chicago as our 27th nonstop destination and the arrival of STARLUX Airlines underscore the confidence airlines have in Ontario International Airport. We are proud to serve as a gateway to Southern California and to offer travelers more options than ever before.”
Aviation analysts point out that ONT’s growth is not just about numbers—it’s about changing the way people travel in Southern California. By providing a less crowded, more convenient alternative to LAX, ONT is attracting both airlines and passengers who value efficiency and comfort.
Historical Context: From Local Control to Regional Powerhouse
ONT’s transformation began in 2016, when control shifted from the City of Los Angeles to the local Ontario International Airport Authority. This move allowed for:
- Focused investment in infrastructure and services
- Aggressive route development targeting both domestic and international markets
- Community engagement to ensure the airport meets local needs
Since then, ONT has added nonstop flights to destinations across the U.S., Mexico, Central America, and Asia, steadily building its reputation as California’s fastest-growing medium/large airport.
Looking Ahead: The Future of ONT and Southern California Travel
More Routes and Bigger Plans
ONT is not slowing down. Airport officials are actively pursuing additional international and domestic routes, with plans to further expand service to Asia, Latin America, and beyond. The airport’s growing passenger base makes it an attractive partner for airlines looking to tap into Southern California’s booming market.
Infrastructure Upgrades
To support rising passenger numbers, ONT is investing in:
- Expanded customs and immigration facilities
- New passenger lounges and retail options
- Improved ground transportation links, including the anticipated Brightline West high-speed rail system, which will connect ONT to Las Vegas and other regional destinations
Regional Economic Impact
The Ontario Convention Center’s planned expansion and ongoing tourism development efforts will work hand-in-hand with ONT’s growth, creating a powerful engine for economic development in the Inland Empire.
