Do airlines charge different people different prices for the same seat? That's what the federal government wants to find out. On Wednesday, the Federal Trade Commission ordered Delta, United and JetBlue to hand over details on how they set fares, including whether things like your browsing habits or your frequent flyer status can change the price you're shown. The three airlines were named alongside Uber, Lyft, DoorDash, Instacart, Target and Walmart, and they have 45 days to respond. That puts the deadline right in the middle of holiday booking season.
What the FTC Is Asking
The FTC isn't accusing anyone of breaking the law, at least not yet. This is what's called a 6(b) study, a fact-finding exercise the agency uses to understand how an industry works. The commission voted 2-0 to send the orders, and companies that don't answer can be taken to federal court.
What it wants to know is whether prices vary from person to person based on personal data. The FTC specifically mentions loyalty program membership, web browsing habits and AI tools that analyze information about customers. Chairman Andrew Ferguson said consumers deserve to know whether companies use their data "to estimate the highest price they can charge each consumer."
How Airline Pricing Works Today
Airline tickets have always changed price, but usually not because of who you are. Airlines split each flight into price levels, and as cheaper seats sell out, the price goes up for everyone. That's why the same flight can cost $200 on Monday and $350 on Thursday. It's frustrating, but at any given moment, everyone searching is supposed to see the same fare.
What the FTC is asking about is different. Personalized pricing, which critics call surveillance pricing, would mean you and the person sitting next to you could be quoted different prices at the exact same moment, because of something the airline knows about you. Maybe you always fly for work, or maybe you've searched the same route five times this week. That's the line regulators want to know if anyone is crossing.
There's already a version of this that airlines do openly. Fares can depend on how many people you're booking for, and a recent analysis found American charging solo travelers more than groups on about a third of the flights it checked. It's not personal data, exactly, but it shows how much more than the seat itself can go into a price.
What the Airlines Say
All three airlines deny doing it. Delta told senators last year that it had never used, tested or planned to use a fare product that targets individual customers with personalized prices based on their data. It has said its AI pricing tools work with overall market and demand information, not your personal details. In a statement this week, Delta said it has "zero tolerance for discriminatory or predatory pricing."
JetBlue says its fares are set by demand and seat availability, and that everyone sees the same fares on its website and app. That hasn't stopped questions, though. In April, JetBlue's social media team told a customer whose fare jumped $230 while booking travel for a funeral to try clearing their cookies or using a private browsing window. JetBlue later said that advice was wrong and apologized, but the episode led to questions from lawmakers and a proposed class-action lawsuit, which JetBlue denies. United hadn't publicly commented on the FTC's order as of Friday.
How to Make Sure You're Getting a Fair Fare
Until the FTC reports back, there's no proof any airline is charging you more because of who you are. Still, a few habits can help you spot it if it ever happens, and they're good practice for finding cheaper fares anyway.
Compare the same flight in more than one place, like the airline's own site and a search tool like Google Flights. Try it both logged into your frequent flyer account and logged out. If you see a different price for the same seat at the same moment, take a screenshot, because that's exactly the kind of evidence regulators want. Setting a fare alert also helps, since it watches the price for you instead of you searching the same route over and over.
Fares are already high for reasons that have nothing to do with personal data, from fuel costs to less competition, as we found with Frontier. The FTC's study won't change what you pay this holiday season. But if it turns up evidence that airlines are pricing people individually, it could be one of the biggest fights over how you buy a plane ticket in years.
