New Gateways to Hawaiian Paradise

The most anticipated additions involve Hawaii. Southwest is adding two new mainland-to-island routes. These flights head straight to Honolulu (HNL). This move turns two California airports into Hawaiian gateways.

First, the route from Ontario/LA (ONT) begins June 4, 2026. This flight will operate on a daily basis. It gives Inland Empire residents a direct path. This avoids the congestion of larger Los Angeles airports.

Second, service from Burbank (BUR) starts August 4, 2026. Flights will operate on peak travel days. This service brings much-needed options to Burbank travelers. The two new routes dramatically increase access to Hawaii. They invite more tourists to enjoy the Aloha State. Hawaiian tourism will see a powerful boost from this access.

Connecting the Coast: North to South

The expansion focuses heavily on the Pacific Northwest. New links from Long Beach will excite travelers. Long Beach (LGB) gains two important new services. These connect California to vibrant northern cities.

One new route flies from LGB to Portland (PDX). The other route flies from LGB to Seattle (SEA). Both services launch on August 4, 2026. They will each operate six times per week. This provides flexibility for quick, six-day trips. These routes connect two massive economic areas. They promote tourism and trade between states. They make weekend Pacific Northwest trips simple and easy.

An important intra-California route is also starting. It connects San Diego (SAN) to Santa Barbara (SBA). This service begins daily on August 4, 2026. It is an ideal flight for quick state getaways. This short flight eliminates long, stressful highway driving. It makes wine country and coastal tourism effortless.

San Diego’s Surge: A Hub for Exploration

San Diego International Airport (SAN) is a major winner. It anchors Southwest’s entire West Coast strategy. The airline is doubling existing daily flight frequencies. This starts on August 4, 2026.

Three crucial routes see this massive increase:

• San Diego (SAN) to Portland (PDX)
• San Diego (SAN) to Seattle (SEA)
• San Diego (SAN) to Salt Lake City (SLC)

Doubling these flights offers more schedule choices. It gives tourists more power over their travel times. It also strengthens San Diego’s role as a vital travel hub. The total number of daily flights from SAN will skyrocket. The airline plans for an all-time high of 139 daily departures. This will happen during the peak travel months of August and September 2026. An airport official said this growth is incredible. They said it solidifies San Diego’s position in global travel. This high frequency signals confidence in Southern California tourism.
