Southwest Hawaii Attacks Alaska/Hawaiian With First New Mainland Routes In Years

Southwest just did something it hasn’t done in years. It opened two new Hawaii gateways, both in Southern California, and both in places where Alaska and Hawaiian either already dominate or have themselves just planted a flag.

Southwest has not opened a new mainland gateway to Hawaii since its 2022 expansion, when it added routes before beginning a multiyear pullback.

After years of retreat across its Hawaii network, Southwest is suddenly back on offense, and the choice of Burbank and Ontario is as much a strategic message as it is new route announcements.

The two routes were revealed early this morning. Daily Ontario to Honolulu flights begin June 4, 2026. Burbank to Honolulu launches August 4, 2026, currently on peak days. These flights are already bookable through September 30, 2026, which gives travelers a long booking window, given how Southwest works.

The airline framed this as part of a broader Southern California strategy, with senior vice president of network planning Adam Decaire, who has long been instrumental in Southwest’s Hawaii plans, saying that new facilities in Burbank, along with onboard enhancements, position Southwest to offer more for customers in the region for years to come.

The Burbank showdown.

Burbank has not had direct Hawaii service in more than twenty years. That alone makes this announcement notable. The more interesting twist is the competitive timing. Alaska announced Burbank to Honolulu last month, with flights set to begin May 13, 2026. Southwest announced the same route almost exactly one month later. For an airport of Burbank’s size, having two carriers launch Hawaii nonstop service in the same season is extraordinary.

The new terminal at Burbank opens in October 2026, which means both carriers are racing to establish footholds before the upgraded facilities come online. This is a battle for Los Angeles Basin customers who are desperate to avoid the stress of LAX. Both airlines know that travelers in the San Fernando Valley and northern LA County have been loyal to BUR for quick security, easy parking, and fewer delays. Hawaii service there has been the missing piece.

Alaska had the field to itself for almost exactly thirty days. Southwest erased that advantage, and it did so by reopening its Hawaii playbook at an airport that aligns perfectly with its identity as the convenience focused, secondary airport specialist.

One big question is how much this sudden glut in inventory could spark a surprise Hawaii airfare war. And we’d assert the chances are very strong.

Ontario goes head to head with Hawaiian.

Ontario to Honolulu is and has long been Hawaiian/Alaska Airlines territory. The carrier operates daily service and has enjoyed a solid niche at an airport that keeps growing, but still feels far more manageable than LAX.

Southwest entering the Ontario route to Honolulu means direct competition for the first time, and it comes at a moment when Hawaiian and Alaska are navigating the most complicated transitions in their history.

Former Hawaiian elites are still sorting out Atmos Rewards, and that shift has created questions, worry, and some outright frustration. Alaska has experienced system outages and groundings at moments when travelers least expected them. This is a period when both brands are far more inwardly focused than is usual.

Southwest sees Ontario as a place where Hawaiian has strong demand. For families and leisure travelers who prefer consistent pricing and simpler airport experiences, Ontario is a near-perfect match. This creates a direct competition scenario that Hawaiian has avoided at ONT for years. It also gives Inland Empire travelers something they have never had: the ability to comparison shop between two carriers with entirely different strengths and offerings.

The reversal after years of retreat.

These new routes mark the first time in years that Southwest has added Hawaii gateways rather than trimming them. Back when it was adding, the airline appeared to reach the peak of its Hawaii ambition. It operated a plethora of new Hawaii routes across mainland gateways including anchor gateways Las Vegas, Los Angeles, and Phoenix. The schedule was aggressive. The expansion was fast. And very quickly, the airline found itself dealing with structural constraints that Hawaii only magnified.

What followed was a multiyear retreat. Route after route was cut between the mainland and Hawaii while interisland flights became fewer with more challenging timing compared with Hawaiian’s massive coverage using its dedicated fleet. At the same time, Southwest ended its long standing free bag policy this year. And, Rapid Rewards was devalued across multiple categories. It has been a series of moves from bold ambition to cautious retrenchment.

Today breaks that trend in Hawaii for the first time. Not only is Southwest adding flights, but it is also adding entirely new gateways that sit directly in the most important geography of the new and previously unchallenged Alaska and Hawaiian network map.

Why Southwest is moving now.

Airlines never say the quiet part out loud, but the timing is simple and deliberate. Alaska and Hawaiian are deep in integration headaches, with loyalty complaints, system outages, and leadership attention pulled inward. Southwest saw the opening and is stepping straight into it the foray.

Southwest unquestionably has its own Hawaii scars, but Burbank and Ontario signal a bet that the competition is far more distracted than it is. Secondary Southern California airports appear tailor made for Southwest’s brand. This lets the airline reenter Hawaii from a position of relative strength right as Alaska and Hawaiian could be the most vulnerable.

The implications for Hawaii travelers.

Competition almost always leads to lower fares, especially in the opening months of a new route. Both Burbank and Ontario have been under competitive pressure for Hawaii service for years, and now each will have two or more carriers vying for attention. This is the kind of environment where introductory fares can be aggressive and where price-sensitive families will benefit the most.

For Burbank, the mere fact that there will be two nonstop carriers after a twenty year gap is a shift. It gives San Fernando Valley travelers a way to avoid LAX on one of the most leisure heavy travel corridors in the country. For Ontario and the enormous Island Empire, it means Hawaiian no longer gets to set the terms alone. That dynamic has been stable for years. Southwest is set to break it. This also marks a subtle but important shift in the Hawaii landscape.

As Alaska and Hawaiian continue to focus on their all-important integration challenges, Southwest may find more opportunities to bring back old Hawaii routes or even test new ones.

Burbank and Ontario were not random choices. They are clearly calculated. They speak to a Southwest strategy built around letting competitors exhaust themselves while Luv picks high value spots where passenger sentiment and convenience play in its favor.

For travelers, this means it may finally be possible to play carriers against each other in markets where there was no competition before. Anyone who lives closer to BUR or ONT than LAX now has options that were unimaginable four years ago.

Will you switch airports or airlines now that Southwest has suddenly stepped into Burbank and Ontario Hawaii flights?
