Thirty years ago, the same system landed airlines in a $1 billion case. - Author: Zach Benitez - Tags: News, Breaking News Ever notice how airfares on the same route all seem to jump at once? A growing airline price fixing lawsuit says that may not be a coincidence. Two proposed class actions now accuse airlines of using a shared industry system to swap sensitive pricing and demand data and keep fares higher than they'd otherwise be. The biggest of them names seven of the largest US airlines: American, Delta, United, Southwest, Alaska, Hawaiian and JetBlue. The airline pricing lawsuit What's Claimed, and What Isn't Proven Airlines named American, Delta, Southwest, Alaska and JetBlue. United isn't named. The claim They shared pricing and demand data through ATPCO, the company that sends fares to booking sites. Proven? Not yet. These are allegations in a new class action, and the airlines can fight them in court. Your ticket Nothing changes when you book. Any payout would likely be a settlement years from now. Been here before In 1994, major airlines and ATPCO settled Justice Department charges of using the same system to signal fare hikes, a scheme the government said may have cost travelers **more than $1 billion**. Contrail --- ## Latest Updates **Saturday, Nov. 7, 12:15 p.m. ET:** The case just got bigger. Reports Friday detailed two proposed class actions over the airlines' data sharing. One, filed in Washington, names seven airlines: American, Delta, United, Southwest, Alaska, Hawaiian and JetBlue. United and Hawaiian weren't among the airlines named in the first reports on Wednesday. The other suit, in Virginia, targets ATPCO itself, its subsidiary 3Victors and a smaller group of airlines, and points to data products called Iris, PriceEye and DemandView. None of the airlines have publicly responded so far, and none of the claims have been proven. --- ## What the Lawsuit Claims The core accusation is that the airlines used a shared industry system to swap information they're supposed to keep to themselves, like how they plan to price seats and how much demand they're seeing on their flights. In normal competition, an airline doesn't know what its rival is about to charge until the fare shows up on a booking site. If airlines can see each other's plans ahead of time, the lawsuit argues, they don't have to compete as hard, and passengers end up paying more. In the lawsuit's telling, it's a bit like a poker game where every player can peek at the others' cards, and the pot is your vacation budget. The full complaint wasn't widely available Wednesday night, so key details, including exactly which data was shared, how much money the plaintiffs are seeking and how many travelers the class covers, aren't public yet. We'll update this page once they are, along with any responses from the airlines. --- ## What Is ATPCO? Chances are you've used ATPCO without ever hearing of it. It might be the most important travel company most travelers have never heard of. It's a company outside Washington, D.C., owned by a group of airlines, that collects fares from more than 440 airlines worldwide and passes them along to the booking sites, travel agents and apps where you actually buy tickets. When you search for a flight on Google Flights or Expedia, a lot of the prices you see have traveled through ATPCO first. Think of it as the pipe that carries airfares from the airlines to you. That's useful, since it's why you can compare dozens of airlines in seconds. The worry, now and in the past, is what else might travel through that pipe. ## Know Before You Fly Delays, strikes, new routes and the airline news that actually affects your trip, explained for normal travelers.

In the early 1990s, the Justice Department accused major airlines of using ATPCO's system to float "trial balloon" fare increases, essentially posting a future price hike, watching whether rivals matched it, and pulling it back if they didn't. The government said it found more than 50 separate price-fixing agreements covering hundreds of routes, and that the scheme may have cost travelers more than $1 billion between 1988 and 1992. The airlines settled without going to trial. United and USAir agreed in 1992, and American, Delta, Northwest, Continental, TWA and Alaska followed in 1994, along with ATPCO itself. The deal banned the kind of signaling the Justice Department described, like filing fares with a future start date. In other words, no more trial balloons. That court order expired in 2004, though its core rules reportedly remain built into ATPCO's system. It isn't the only time either. In 2018, Southwest and American agreed to pay a combined $60 million to settle a separate lawsuit accusing major airlines of coordinating to keep seat numbers down, without admitting any wrongdoing. Airlines have a long history of being accused of moving together. Proving it in court is a different story. --- ## What It Means for Your Next Ticket For now, nothing changes when you book. A class action is the start of a long process, and the airlines will almost certainly fight it. Don't spend that settlement check just yet. If the case goes anywhere, the payoff for travelers would most likely be a settlement years from now, not cheaper fares next week. It does land at an awkward moment for the industry. Holiday fares are [the most expensive in a decade](https://www.thecontrail.org/holiday-flight-prices-2026-when-to-book/), airlines keep saying prices won't fall [even when fuel gets cheaper](https://www.thecontrail.org/why-airfares-are-still-so-high-even-when-fuel-prices-drop/), and [the Federal Trade Commission is already asking](https://www.thecontrail.org/do-airlines-charge-different-prices-ftc/) Delta, United and JetBlue how they set fares. Regulators and travelers alike seem to be asking the same question: who's really deciding what you pay? In the meantime, the best defense is the boring one. Compare prices across a few sites, set fare alerts and remember that when every airline on a route charges almost exactly the same price, you're not imagining it. Whether that's competition or something else is now up to a judge.
