Kauai And Kona Gain Nonstops While Honolulu To Maui Loses Half

If you’re planning a trip to Hawaii next year, the plans you had yesterday may already be out of date. We read the Hawaii schedule as soon as the new dates opened on Southwest yesterday, July 16. The schedule now runs through April 5.

Two things stood out right away. San Diego picked up nonstop service to Kauai and Kona, while Honolulu to Maui dropped by 50%, from 8 daily flights to 4 in each direction. One mainland gateway gained reach while the busiest route in the state lost half its frequency, all in the same schedule. These will have a significant impact on Hawaii visitors and residents alike.

The Southwest San Diego additions are part of a larger route announcement, but the airline has said nothing about the multiple interisland reductions that showed up in the same schedule. So everything below separates what the schedule shows from what we think the larger Hawaii pattern may suggest.

San Diego suddenly reaches both Kauai and Kona.

The easiest and most positive change here is that, beginning with travel in March 2027, Southwest will again be selling nonstop flights between San Diego and Kona. At the same time, the airline is also bringing back nonstop service between San Diego and Kauai, giving travelers two more Hawaii destinations to reach without first flying through either Honolulu or another gateway.

Both San Diego routes are weekend service, in the new block rather than throughout the week. That timing points toward spring break and weekend leisure travelers rather than everyday demand, and it will be worth watching whether these flights become year-round or run only through the peak season of summer.

These are not first-time routes either. Southwest flew San Diego to both Kona and Kauai before dropping them in 2022, so what looks like expansion is really a revival of service the airline had already cut once. That launch, then cut, then bring back again pattern is one that Southwest has repeated in Hawaii.

Las Vegas gets an overnight flight that runs the wrong direction.

One more Hawaii item in the same announcement stands out just for how unusual it is. Beginning in March, Southwest will operate a westbound overnight flight from Las Vegas to Honolulu, departing at 2:45 a.m. and arriving at 6:10 a.m. in Hawaii. Most overnight flights run eastbound, where the time change lets a plane leave late and arrive the next morning, which is why the very popular and frequent red-eyes Hawaii travelers know go from the islands back to the mainland.

A westbound overnight into Honolulu runs counter to that and is unusual enough to raise eyebrows, though the early arrival does give travelers a nearly full first day on the ground.

Useful Hawaii route competition.

For Southern California travelers, the return is useful. A nonstop to Kona or Kauai removes a connection and creates two more ways to reach Hawaii, even if those choices are limited to weekends for now.

More importantly for many, these routes compete with flights on Alaska Airlines. Therefore, we anticipate at least some help with otherwise sky-high airfare prices.

Interisland flying moves the other way as expected.

The Honolulu-Maui cut we noted up top is the most impactful single change in the new schedule, and it is worth seeing in context. Southwest has been running 8 daily flights on most days between Honolulu and Kahului, Hawaii’s single busiest route, and the new schedule results in just 4 daily flights beginning in March on not only the busiest route in Hawaii but also one of the most trafficked in the country.

Maui-Kauai flying changes too. Nonstop service between Kahului and Lihue disappears after March 10 in the schedule we reviewed, removing an option that had allowed travelers and residents to move between Maui and Kauai without routing through Honolulu. That also reduces competition such that only Hawaiian will be flying that route.

Schedules can still change before flights operate, so we’re reporting what Southwest is showing as available for sale today rather than saying that every frequency noted is final. Even then, the direction here is hard to miss, with mainland flying being restored in one part of the mainland network, with some of the shortest Hawaii routes being reduced or removed.

Southwest is again changing Hawaii flying.

When Southwest arrived in Hawaii in 2019, growth was the whole story, with the airline adding mainland routes, expanding interisland service, and quickly becoming a true competitor across the islands. Nearly every one of its early schedule extensions added more Hawaii flights than the previous one.

The schedule that opened yesterday takes a far more measured approach, restoring mainland reach in places like San Diego while portions of the interisland operation keep shrinking. Las Vegas, meanwhile, still looks like one of Southwest’s hottest Hawaii gateways. This comes as the airline is still deciding where its Hawaii aircraft belong rather than committing to a steadier plan. Southwest previously acknowledged that Hawaii has not performed as strongly financially as the airline once expected, particularly compared with markets closer to its traditional mainland strongholds.

Why San Diego is becoming more important.

The returning Kona and Kauai flights raise a bigger question about Southwest’s Southern California strategy. San Diego may be taking on more of the Hawaii role it once spread among other California airports.

San Diego also sits within one of Southwest’s stronger traditional regions. Building more Hawaii flying there could let the airline concentrate passengers through a market it already knows well instead of maintaining thinner service over a wider list of west coast airports.

The flights are only showing in the schedule now available through April 5, 2027. So we don’t yet know whether they will continue as Southwest opens its next booking blocks or whether they are aimed specifically at seasonal Hawaii leisure travel demand.

What early 2027 Hawaii travelers should take note of.

Obviously, the San Diego nonstops are a plus in multiple ways, including competition. But for anyone planning island-hopping, the new schedule has significant limitations. A trip that once connected using the Maui- Kauai nonstop or used the popular Honolulu-Maui route leaves fewer options to choose from.

Had you already spotted these changes in relation to your own Hawaii flights on Southwest? Are the returning San Diego nonstops useful to you, or is the interisland route downsizing something you are disappointed to lose?
