People who bought domestic tickets from American, Delta, United, Southwest, Alaska or JetBlue may be covered by two proposed class actions alleging the airlines pooled non-public fare and shopping data through the airline-owned company ATPCO and its subsidiary 3Victors to keep domestic airfares high. No class has been certified and there is nothing to file yet.
Allegations Only · No Settlement Yet
This article describes two class action complaints. The statements below are unproven allegations. ATPCO, 3Victors and the airlines have not been found liable, there is no certified class, and nothing to claim at this time. This page is informational and is not legal advice.
What Is This About?
Two proposed class actions filed in early November 2026 accuse six of the largest U.S. airlines of using a shared data hub to monitor one another's prices and keep domestic fares high. The hub is the Airline Tariff Publishing Company (ATPCO), which is owned by airlines, and its subsidiary 3Victors.• Brown v. Airline Tariff Publishing Company d/b/a ATPCO, No. 1:26-cv-03646, was filed November 3, 2026 in the U.S. District Court for the Eastern District of Virginia, Alexandria Division. It names ATPCO, 3Victors, American, Delta, Southwest, Alaska and JetBlue.
• Ward v. Airline Tariff Publishing Company, No. 2:26-cv-04289, was filed November 4, 2026 in the U.S. District Court for the Western District of Washington in Seattle. It names ATPCO, 3Victors, Delta, United, American, Alaska, Hawaiian, Southwest and JetBlue.
Both complaints claim violations of Section 1 of the Sherman Act and seek triple damages and a court order ending the alleged data exchange. Both are at the earliest stage: the defendants have not yet answered, and no judge has ruled on the claims.

What Do the Lawsuits Allege?
ATPCO has long been the industry's central fare database. Airlines file their published fares and rules through it, and it distributes that data to travel agents and booking systems. The complaints say the dispute is not about airlines watching each other's published fares, which has long been possible through ATPCO. Instead, they allege the airlines began sharing private data that rivals could not otherwise see:• Shopping data. This is the record of what travelers search for and the fares each airline offers in response, including dynamically generated prices that are never published. The complaints say ATPCO announced in July 2023 a cloud "clean room" where participating airlines could analyze their "collective shopping insights."
• 3Victors and Iris. ATPCO bought 3Victors in December 2023. Its Iris repository pools shopping data contributed directly from airline systems. The complaints quote 3Victors as describing participation this way: "the more you contribute, the more you receive."
• PriceEye and DemandView. PriceEye is a dashboard that, according to the complaints, flags "anomalies" where an airline's fare differs from its rivals' and ranks them by revenue impact. DemandView, launched October 5, 2026, shows where search demand is building before it turns into bookings.
The plaintiffs argue this "give-to-get" exchange removes the uncertainty that would otherwise push airlines to undercut each other. They claim a fare cut can now be spotted and matched quickly, so there is less reason to offer one. The Brown complaint alleges the arrangement began no later than July 25, 2023. It cites the plaintiffs' own analysis of Bureau of Transportation Statistics data: the average one-way fare across 693 U.S. routes rose 30.7%, from $198.71 in early 2022 to $259.66 in early 2026. These are the plaintiffs' allegations and figures, not findings by any court.
Has ATPCO Faced This Before?
Yes. In December 1992, the U.S. Department of Justice sued ATPCO and eight airlines. It alleged they used ATPCO's fare system to signal and negotiate fare increases. The case ended in consent decrees that limited what fare information could be shared through ATPCO. According to both complaints, those decrees expired in 2003 and 2004. The new lawsuits argue that ATPCO's move into pooled shopping data recreates the kind of information-sharing those decrees restricted.Who Could Be in the Class?
The two complaints define their proposed classes differently.• Brown (Virginia): all people and entities in the United States that bought a ticket for travel between two U.S. points from American, Delta, Southwest, Alaska or JetBlue, directly or through an agent acting for the airline. The class period runs from November 1, 2022 until the effects of the alleged conduct end.
• Ward (Seattle): two classes of people who bought one or more tickets for U.S. domestic travel within the past four years. One class covers tickets from Southwest, Alaska or JetBlue, and the other covers tickets from United.
United is a defendant only in the Seattle case. The Brown complaint says United's contract of carriage requires passengers to give 60 days' notice before suing. The plaintiffs say they dispute that requirement but intend to give notice, and they list United as a possible co-conspirator for now. The Ward complaint sues Delta and American as ATPCO owners and participants, but neither of its proposed classes is defined by tickets bought from them. Both complaints exclude the defendants, their affiliates, government entities and the judges assigned to the cases.
What Have the Airlines Said?
None of the defendants had filed a response in court as of November 7, 2026. According to news reports, American Airlines told The Seattle Times that it develops and prices its products independently. No other defendant had commented publicly in the reports OCA reviewed. As a general rule of antitrust law, courts treat a company independently matching a rival's public price as lawful, so the cases will turn on whether the plaintiffs can show an agreement to exchange competitively sensitive information.What Happens Next?
The next step is for the defendants to be served and to respond to the complaints. Two similar cases are now pending in different federal courts. Any class would have to be certified by a judge before anyone could be paid. No settlement, payment or claim process exists, and no court date has been announced.OCA also covers a separate, earlier antitrust case over airline seat capacity, the domestic airlines price-fixing settlement, and the JetBlue "surveillance pricing" lawsuit over data-driven fares.
Questions
Is there an airline price-fixing settlement to claim from ATPCO or the airlines?
No. Both cases were filed in early November 2026 and are at the complaint stage. No class has been certified, no court has ruled on the allegations, and there is no settlement or claim form.
Which ticket buyers do the proposed classes cover?
The Brown complaint proposes one class of people and businesses in the United States that bought a domestic ticket from American, Delta, Southwest, Alaska or JetBlue from November 1, 2022 onward. The Ward complaint proposes two classes covering domestic tickets bought in the past four years: one for Southwest, Alaska or JetBlue tickets and one for United tickets. A court would decide later whether any class is certified and on what terms.
Why is United left out of the Virginia case?
The Brown complaint says United's contract of carriage requires passengers to give United notice of a dispute and wait 60 days before suing. The plaintiffs say they do not agree the requirement is valid but intend to notify United, and they list it as an unnamed possible co-conspirator for now. United is a named defendant in the Seattle case.
Is it illegal for airlines to watch each other's fares?
Not by itself. Airlines have long seen each other's published fares through ATPCO, and the Brown complaint says it does not challenge that. Both lawsuits target the alleged pooling of non-public shopping data and dynamically generated prices. Courts generally treat airlines independently matching a rival's public price as lawful, so the plaintiffs will have to show an agreement to exchange competitively sensitive information.
