Book a flight from an iPhone, in a hotel lobby, at midnight, after refreshing the same search four times because the price keeps changing, and Delta might quietly decide you look desperate enough to pay more. Sounds like a conspiracy theory. It isn’t anymore. It’s the subject of a congressional inquiry with an actual deadline.
Eight airlines, American, Delta, United, Alaska, JetBlue, Southwest, Frontier, and Hawaiian, got formal letters this month from Rep. Frank Pallone asking them to explain whether they’re using AI and personal data to set your ticket price individually rather than pricing the seat. They have until August 25 to answer. The Senate held hearings on the same question, and the FTC has been sniffing around since 2024. A lawsuit against JetBlue claims the tracking goes deeper than most people assume: mouse movements, keystrokes, how long you linger on a page, what device you’re using, even your location. One study cited in the reporting found this kind of pricing can boost airline revenue by up to six percent. Guess whose pocket that six percent comes out of.
Here’s the part that gets me. Airlines already turned buying a plane ticket into a psychology experiment. Seat selection is extra. A bag is extra. Boarding earlier than the group they invented specifically to make you pay for boarding earlier is extra. And that’s all stuff you can see and decide to skip. This is different. This is the price itself moving based on whether you searched five times in a row, whether you’re on an iPhone, whether the algorithm has decided your browsing pattern smells like someone who has to be in Cleveland by Friday no matter what it costs.
You can’t opt out of a price you don’t know is personalized. That’s the whole trick. A coupon code is a deal you choose to take. A hidden markup based on your device and your desperation is a deal you didn’t know you were losing.
And airlines are just the visible edge of it. The FTC’s broader surveillance-pricing investigation covers retailers well beyond air travel, so if you’ve ever wondered why the same pair of shoes shows a different price on your phone than on your laptop, this is why. Companies used to guess what the market would bear. Now they don’t have to guess. They just watch you shop and charge you exactly what you, specifically, will bear.
Congress asking airlines to explain themselves by a deadline is a decent start, but a strongly worded letter isn’t a law. Nothing stops this practice today, and nothing will until there’s an actual rule that says a price has to be a price, not a guess about how badly you need the thing. Until then, assume every fare you see was written for you personally, and not in a flattering way.
My two cents: clear your cookies, use a browser you don’t shop in, and stop refreshing the search page like it’s going to reward your patience. It’s watching you do that too.
