Why is Southwest Airlines increasing connectivity between California and Hawaii?

The Airline is doing it as a strategic move to grow its market share in California. It will help the Airline to expand its service to a popular leisure destination. The new route is planned to meet the growing demand. The aviation industry saw a growing demand for travel between California and Hawaii. An increase in leisure/ business travel post-pandemic has boosted flight demand. The Airline will be able to leverage new facilities in Southern California (particularly in the Los Angeles area). The Hawaii route addition will offer more choices to both mainland and inter-island passengers.

How is Southwest Airlines growing its West Coast Presence through Ontario International Airport?

Southwest Airlines is adding new routes apart from increasing its flight frequency on the West Coast. This has been possible because Southwest has become the largest carrier at Ontario International Airport (ONT). It is the second-most-popular mid-sized Airport (in Southern California). Southwest carried approximately 36% of ONT’s passengers in 2024. The Airline will complete its 40-year partnership with the Airport in 2025. Nonstop service to Honolulu by the Airline has been a milestone achievement. The new route cements Southwest’s partnership with ONT. Ontario International will mark the 10-year anniversary of local ownership soon.

Who is the major competitor of Southwest Airlines on the West Coast?

Southwest Airlines faces major competition from Alaska Airlines. Alaska Airlines is already operating various flights on the West Coast, including the Hawaii route. The new addition from Southwest Airlines meets the growing demand from Hawaiian travelers in Alaska Airlines’ turf. United/ Delta/ American Airlines also give tough competition due to a significant presence in the region.
