Airlines and ATPCO face class actions alleging fare data exchange restrained competition

Seven major U.S. airlines, the industry-owned Airline Tariff Publishing Company (ATPCO) and its subsidiary 3Victors, Inc. are defendants in a proposed class action filed on November 4, 2026, in the U.S. District Court for the Western District of Washington in Seattle. The complaint, Ward and Morris v. Airline Tariff Publishing Company, et al., No. 2:26-cv-04289, alleges that the carriers pooled non-public pricing and shopping data through ATPCO products in violation of Section 1 of the Sherman Act.

The airline defendants are American Airlines Group Inc., Delta Air Lines, Inc., United Airlines, Inc., Alaska Air Group, Inc., Hawaiian Holdings, Inc., Southwest Airlines Co. and JetBlue Airways Corporation. The plaintiffs are represented by Hagens Berman Sobol Shapiro LLP, with Steve W. Berman among the attorneys signing the complaint.

A related proposed class action, Brown v. Airline Tariff Publishing Company d/b/a ATPCO, was filed on November 3, 2026, in the U.S. District Court for the Eastern District of Virginia (No. 1:26-cv-03646). That case names ATPCO, 3Victors, American, Delta, Southwest, Alaska and JetBlue, but not United.

The alleged mechanism

ATPCO, based in Herndon, Virginia, has long distributed published airline fares. The Seattle complaint alleges ATPCO is owned by a group of airlines that includes American, Delta and United. According to the plaintiffs, the challenged conduct is not the public fare-filing system but a newer layer of shopping-data products that sits beside it.

The complaint describes data pooled in ATPCO-administered AWS Clean Rooms and in a central repository called Iris, which 3Victors operates on a contribution model; the complaint quotes 3Victors as saying "the more you contribute, the more you receive." ATPCO acquired 3Victors in or about December 2023. Subscribers allegedly receive competitive intelligence through a product called PriceEye, including pricing alerts, competitive benchmarking and anomaly detection. The complaint alleges Alaska signed a PriceEye agreement in or about July 2024, that Iris was introduced in December 2024, and that the PriceEye dashboard has delivered competitor prices since July 2025.

The plaintiffs characterize the arrangement as "a new, highly sophisticated information exchange to monitor one another's pricing." They allege that fares rose once the tools were fully rolled out and that 2026 was the first full year with every feature in place. The complaint defines the relevant market as U.S. domestic air travel and points to the Justice Department's 1992 case against ATPCO and eight airlines, which ended in consent decrees limiting how fare information could be shared.

Classes and relief

The Seattle suit proposes two classes of domestic ticket buyers from the last four years: one for purchasers from Southwest, Alaska or JetBlue, represented by Ashley Ward of Temecula, California, and one for purchasers from United, represented by Gregory Morris of Rockaway, New Jersey. The Southwest, Alaska and JetBlue class sues ATPCO, 3Victors, American, Delta, United and Alaska, treating Southwest and JetBlue as alleged co-conspirators. The United class sues ATPCO, 3Victors and the other airline defendants except Hawaiian. Hawaiian Holdings is named as a defendant but is not listed in any count. The complaint pleads four Sherman Act counts.

The plaintiffs ask the court to certify the classes, declare the conduct unlawful, award damages, permanently enjoin the defendants from continuing the conduct, and grant interest, costs and attorneys' fees. They demand a jury trial. No class has been certified, and no defendant had responded to either complaint as of November 7, according to OpenClassActions.

What this means for in-house counsel

The theory here does not depend on any direct agreement to set prices. It targets the sharing of competitively sensitive, non-public data through a jointly owned platform, a theory that has also been raised against algorithmic pricing vendors in other industries. Companies that contribute data to industry benchmarking services, clean rooms or analytics tools on a contribute-to-receive basis should review what they send, how current and granular it is, and what competitors can see in return.

The structure of the Seattle complaint is also worth noting. Each class largely pursues carriers other than the ones its members bought from, while naming its own sellers as alleged co-conspirators. Legal teams that rely on customer contracts to channel or limit antitrust claims should not assume those terms will keep a company out of a conspiracy case brought by a rival's customers.

Finally, executives' public statements about pricing power can end up in a complaint. The Seattle filing cites public remarks by airline executives about fares and capacity. Counsel should brief investor relations and senior management on how comments about industry pricing discipline may be read in litigation.
