We’ve spent nearly 20 years comparing airfares to and from Hawaii, and sometimes the results make little sense. Competing airlines advertise identical prices, and now two new federal lawsuits accuse major airlines of exchanging sensitive pricing information that competitors ordinarily wouldn’t see, potentially reducing the incentive to offer lower fares.
The 99-page complaint filed November 4 in Seattle names Alaska Air Group, Hawaiian Holdings, Southwest, United, Delta, American, and JetBlue, along with airline pricing company ATPCO and its subsidiary 3Victors. A separate lawsuit filed in Virginia earlier that week makes similar allegations against a somewhat different group of defendants. Both accuse the companies of violating federal antitrust law, although neither identifies specific Hawaii routes where fares were allegedly inflated.
In our May 2026 article, Hawaii Just Quietly Lost Its Last Airline Fare Wars, we described searching for flights from Lihue to Honolulu for our own June travel. Round-trip fares were running about $230 per person, even though both competitors showed plenty of available seats. It was a frustrating example of how much interisland travel had changed.
Alaska’s connection to ATPCO goes back years.
In May 2022, we reported that Alaska Airlines had selected ATPCO’s Architect pricing system, designed to help airlines manage fares more efficiently. Alaska revenue management executive Kirsten Amrine described how the technology would help the airline become more strategic and unlock the full revenue potential of its network.
We examined that agreement in Dynamic Pricing Just Drove Your Hawaii Airline Ticket Sky-High, and returned to the subject repeatedly as pricing technology developed. The relationship was public, and using such software to manage fares has become standard airline practice.
In December 2023, ATPCO acquired travel-data company 3Victors. The following July, 3Victors announced that Alaska had signed up for PriceEye, a product providing competitive fare information to airline pricing departments. Alaska’s director of revenue management, Dante West, praised the product’s data quality and timeliness following a successful trial. The Seattle complaint cites that announcement specifically in paragraph 134.
The PriceEye agreement preceded the later introduction of a data-sharing repository called Iris. It documents Alaska’s commercial relationship with 3Victors, but doesn’t establish whether Alaska subsequently contributed information to Iris or engaged in any unlawful conduct alleged.
What airlines could see that passengers couldn’t.
Airlines have always watched competitors’ advertised fares. When Southwest announces a discounted Hawaii ticket, Hawaiian can see it and independently decide whether to match the price. That is normal competitive behavior, and it isn’t what makes these lawsuits stand out.
The allegations concern prices generated in response to individual flight-shopping requests, including offers that might never appear in an ordinary public fare search. The plaintiffs claim that competing airlines obtained access to detailed information about those offers through a shared system rather than having to discover prices for themselves.
3Victors describes Iris as a repository of shopping information from airline systems, travel agencies, and other sources, while PriceEye provides competitive pricing analysis. According to the company’s own description, customers contributing shopping information can receive more extensive competitive data in return. The company puts it plainly: “The more you contribute, the more you receive.”
The plaintiffs argue that this “reciprocal exchange” could allow airlines to spot competitors’ lower prices quickly, including some discounts they otherwise might never discover. An airline considering cutting fares to fill seats could become less willing to do so if competitors could immediately see and respond to those offers.
Better information about competitors can also help an airline lower its prices to win over passengers. The existence of a shared data product does not, by itself, establish that participating airlines used it to suppress competition, which is what the plaintiffs must now prove.
Hawaiian’s connection is less direct than Alaska’s publicly documented PriceEye agreement.
The Seattle complaint alleges, based on information and belief, that Hawaiian participated in the information exchange through the technology or ATPCO’s governance. It points to former Hawaiian chief revenue officer Brent Overbeek, who actually served on ATPCO’s board before Alaska completed its acquisition of Hawaiian in September 2024.
His board position is documented, but the complaint doesn’t identify a comparable public announcement establishing that Hawaiian ever separately purchased PriceEye. Southwest also appears in the filing through an April 2026 industry presentation about the product, although that presentation doesn’t establish anything further.
American Airlines has rejected the new allegations, saying it develops and prices its products independently and competes to win customers. The other companies have not yet presented their full defenses in court, and no court has determined that the information exchanges described by the plaintiffs violated antitrust law.
The Seattle lawsuit proposes groups of domestic ticket purchasers involving Southwest, Alaska, JetBlue, and United over approximately the past four years. The Virginia case proposes different purchaser groups. No class has been certified, and no settlement or refund program exists for travelers at this point.
This isn’t ATPCO’s first federal antitrust confrontation.
In December 1992, the Justice Department sued ATPCO and eight major airlines, including Alaska, American, Delta, and United, alleging they used a shared fare-distribution system to communicate planned pricing changes and restrict competition.
The government argued that advance fare information helped airlines signal planned increases or discount reductions and see whether competitors would follow. The litigation resulted in consent decrees in 1993 and 1994 that restricted certain practices, rather than a trial establishing liability. Those decrees, however, subsequently expired. The plaintiffs in the new cases argue that far more sophisticated technology has now recreated some of the earlier competitive concerns.
What we’ve actually seen with Hawaii airfares.
The change in Hawaii fare competition is impossible to ignore. Southwest’s arrival brought extraordinary mainland and interisland discounts, including $39, $49, $79 and $99 promotional fares, but that period of aggressive competition has faded entirely.
Our October 27 article, Hawaii Airfares Keep Changing. Are Your Searches To Blame?, examined how airlines use shopping information to anticipate demand. We found no evidence that repeatedly checking a particular flight causes an airline to raise that individual’s ticket price. The new lawsuits address a different concern involving information potentially exchanged between competing airlines themselves.
Our own fare comparisons haven’t always shown airlines matching one another. In May 2025, for example, Southwest was asking $110 between Lihue and Hilo while Hawaiian wanted $208 for roughly comparable flights. Since then, by our own observations, those differences are largely gone. Airlines can independently match publicly advertised fares, and fuel costs, demand, and capacity also impact what people pay.
Have you recently compared Hawaii airfares and found competing airlines quoting exactly the same price, or dramatically different ones?
Tell us the route, approximate dates, and prices you found in the comments, especially if you’ve noticed something surprising when searching again.
