Southwest Airlines will introduce daily nonstop service between Ontario International Airport in Southern California and Honolulu beginning June 4, 2026. The new route broadens travel access for California residents and strengthens one of the busiest leisure travel corridors in the United States.
The airline plans a morning departure from Ontario and an evening return from Honolulu. This schedule offers flexibility for both vacationers and business travelers, while adding much-needed seat capacity for the growing California–Hawaii market.
Strengthening Southwest’s Footprint at Ontario Airport
Ontario International Airport (ONT) continues to expand as a major regional hub. It remains one of the fastest-growing airports in the country, supported by increasing passenger volumes and its convenient location east of Los Angeles.
Southwest Airlines is the largest carrier at ONT and has played a central role in the airport’s development. In 2024, the airline carried more than one-third of all ONT passengers. The introduction of the new Honolulu route reinforces a partnership built over four decades and aligns with the airport’s broader strategy to expand long-haul and high-demand destinations.
As ONT celebrates nearly a decade of local ownership, this route highlights ongoing growth and rising traveler confidence in the airport’s accessibility, efficiency, and competitive airline offerings.
Modern Aircraft and Upgraded Passenger Experience
Southwest will operate the Ontario–Honolulu route with its Boeing 737 MAX 8 fleet. The aircraft features 175 seats, improved fuel efficiency, and modern cabin amenities designed for long-haul comfort. Travelers can expect in-seat power, generous overhead space, and free onboard entertainment.
By early 2026, Southwest will also offer assigned seating across its network. This shift will let passengers choose from standard, preferred, and extra-legroom seating. The upgrade adds flexibility for families, groups, and frequent flyers seeking a smoother boarding experience.
The combination of enhanced seating options and modern aircraft makes the new Honolulu route appealing for travelers wanting a comfortable, tech-enabled journey.
Rising Demand for Hawaii Travel
California remains the largest mainland gateway to Hawaii. Demand continues to rise, driven by year-round tourism, family travel, and increased remote-work mobility. Honolulu, home to Daniel K. Inouye International Airport, is the state’s main entry point and one of the most visited destinations in the Pacific.
The new Southwest route helps meet this growing demand, especially for inland-Southern California residents who prefer avoiding the congestion of Los Angeles International Airport. With more nonstop flights, travelers gain easier access to island vacations, inter-island connections, and business travel opportunities.
A Convenient Alternative to Los Angeles International Airport
Ontario International Airport offers a less crowded and more efficient alternative to LAX. Located about 35 miles from downtown Los Angeles, the airport provides faster security lines, easier parking, and shorter walking distances.
For families, leisure groups, and travelers from Riverside County, San Bernardino County, and eastern Los Angeles County, ONT’s location reduces the stress often associated with larger airports. Southwest’s new Honolulu service enhances ONT’s growing role as a convenient departure point for long-haul leisure travel.
Boosting California–Hawaii Connectivity
The Ontario–Honolulu launch supports Southwest’s continued expansion along the West Coast and its broader plan to increase connectivity between California and the Hawaiian Islands. The new service complements Southwest’s existing flights to Honolulu from Los Angeles, Long Beach, San Diego, and Oakland.
More nonstop flights improve schedule options, reduce layover times, and expand access to competitive fares. The added capacity also helps support Hawaii’s tourism sector, which remains a key contributor to the state’s economy.
What Travelers Can Expect in 2026
Travelers preparing for the new route can look forward to:
- Daily nonstop flights between ONT and Honolulu
- Morning departures from Ontario and evening returns from Honolulu
- Boeing 737 MAX 8 aircraft with modern amenities
- Assigned seating, debuting in early 2026
- Affordable fare options tied to Southwest’s customer-friendly policies
The launch offers another incentive for early travel planning as summer 2026 approaches.
A New Chapter for West Coast Island Travel
Southwest Airlines’ new Ontario–Honolulu route marks a significant step in expanding travel choices for Southern California. The service provides a faster, simpler path to Hawaii and reinforces ONT’s growing importance as a regional gateway.
With demand for Hawaii travel continuing to climb, the June 2026 launch gives travelers more freedom, more comfort, and more direct access to one of the world’s most beloved island destinations.
