Las Vegas-Hilo Route Launched by Southwest Airlines, Reopening Direct Access to Hawaii’s Big Island

Published on December 22, 2025

Southwest Airlines is bringing Hilo, on the Big Island of Hawaii, back into its mainland flight network with a new Las Vegas to Hilo route. This new route marks a significant step in restoring mainland connectivity for Hilo, making travel more accessible for residents, visitors, and business travelers alike. Southwest’s move provides much-needed access to the island, offering increased flexibility for travelers heading to and from this scenic destination.

Reconnecting Hilo to the Mainland

For years, Hilo’s remote location on Hawaii’s Big Island made it harder for travelers to get direct access to the mainland. While Hilo has seen flights to Honolulu and other islands, direct connections to major cities on the U.S. mainland were limited. However, Southwest Airlines’ new Las Vegas route is set to change that. With Las Vegas being a popular travel hub, this new service will significantly cut down travel time for those who need to get to the Big Island from major U.S. cities.

Starting in 2026, the new nonstop service between Las Vegas McCarran International Airport (LAS) and Hilo International Airport (ITO) will provide travelers with a seamless connection to one of Hawaii’s most vibrant destinations. The route will be a game-changer for both leisure and business travelers, offering more direct flight options for those wishing to explore Hawaii’s hidden gems and cultural richness.

What Travelers Can Expect from the New Route

The new route will be seasonal, with flights initially running multiple times a week. Passengers can look forward to Southwest’s signature affordable fares, comfortable seating, and the airline’s easygoing service, all while enjoying the added convenience of flying directly into Hilo.

Hilo, with its lush rainforests, beautiful waterfalls, and volcanic landscapes, is a popular destination for travelers seeking a quieter, less commercialized experience compared to other Hawaiian destinations. The new Las Vegas to Hilo route opens up opportunities for those interested in the island’s ecological wonders, such as the Hawaii Volcanoes National Park and stunning beaches like Punalu’u Black Sand Beach.

In addition, Hilo’s proximity to other parts of the Big Island, including Kailua-Kona and Waimea, makes it an ideal base for exploring the entire island. This connectivity is expected to boost tourism to Hilo and surrounding areas, providing an economic boost to local businesses.

Benefits for the Hilo Community

For Hilo residents, the restoration of mainland connectivity through Southwest’s new route provides more options for visiting family members, business travel, and vacations on the U.S. mainland. The new Las Vegas route could serve as a gateway for students attending universities or individuals with family or business connections in cities such as Los Angeles, San Francisco, or beyond.

Southwest’s expansion into Hilo also promises to increase the airline’s presence on the Big Island, further solidifying its role in providing low-cost air travel options for residents and visitors alike.

Why the Las Vegas Route Makes Sense

Las Vegas has long been a hub for connecting flights to various parts of the U.S. and the world, and Southwest’s decision to add Hilo to its list of destinations makes perfect sense. The city sees millions of visitors each year, many of whom come from the West Coast and surrounding areas — regions that are already accustomed to flying with Southwest. By offering a direct flight from Las Vegas to Hilo, Southwest is tapping into an established market and ensuring a seamless connection for both visitors to Hawaii and local travelers.

Moreover, Las Vegas’ tourist appeal, combined with the easy access to mainland U.S. cities, positions this new route as a convenient and attractive option for people planning vacations or business trips to Hilo. The flight will cut out layovers, saving valuable travel time.

The Impact on Hawaiian Tourism

This route comes at a time when the Hawaiian tourism industry is seeking ways to diversify its visitor base and ease congestion at major airports like Honolulu. Hilo, often overshadowed by its more famous neighbors, stands to benefit from more visitors interested in experiencing the island’s natural beauty and cultural heritage. By providing more efficient access to this picturesque part of Hawaii, Southwest Airlines is helping create a more balanced flow of tourists throughout the islands.

This flight route is also expected to boost local tourism businesses, including those in hospitality, retail, and excursions, by bringing more travelers to the area. As the popularity of eco-tourism and natural experiences grows, Hilo stands poised to become an even more attractive destination for those seeking adventure and relaxation in a less commercialized environment.

Challenges and Considerations

While the new Las Vegas to Hilo flight route offers many advantages, there are some considerations for travelers. The seasonal nature of the route could affect travelers who are planning trips outside the peak travel periods. As with any new flight route, it will take time for both tourists and residents to adjust to the new options, and the airline will likely adjust its service frequency based on demand.

Additionally, while Southwest’s low-cost model is appealing, travelers should keep in mind that Hilo’s smaller airport might not offer the same level of amenities and services as larger Hawaiian airports. However, this is typical for many regional airports, and the focus on the natural experience is what makes Hilo a unique destination.

Conclusion

Southwest Airlines’ new Las Vegas to Hilo route offers exciting new opportunities for travelers seeking to explore Hawaii’s Big Island. With more direct flights available, tourists can enjoy the stunning beauty of Hilo and its surroundings with less hassle and more affordability. The new route benefits both travelers and the local community, supporting economic growth and enhancing connectivity to one of Hawaii’s most unique and tranquil destinations.
