Hopper's booking screen showed a total price at the top, a green "Swipe to Book" button, and two fee toggles hidden below the fold, pre-selected. The company's own tagline: "the travel app with no hidden fees." The FTC put a $35 million price on the gap between those two facts.
"Be transparent and the customer will trust you." Most operators who have built something have heard a version of that line. It sounds right. It is not.
The Default Does the Selling
There is a name for this in the literature. In 2003, Eric Johnson and Daniel Goldstein published a study in Science called "Do Defaults Save Lives?" They tested organ donation consent across opt-in and opt-out systems. A single flip, from "check the box to donate" to "check the box to opt out," moved consent from 42% to 82%. Same people. Same stakes. The only change was the default.
The pattern is called the default effect. People stay with what is pre-selected. Not because they agree with it. Because changing it takes effort, and the pre-selected choice feels like someone already made the call.
Hopper's own internal A/B tests mapped straight onto that finding. When the tip fee was shown and left unselected, 0.75% of users paid it. When it was shown and pre-selected, 43% paid. When it was hidden below the fold and pre-selected, 75% paid.
Same fee. Same users. The only thing that changed was the default and where it sat on the screen. The research is clear on this. The default did the selling.
What the People Inside Knew
In internal emails, Hopper employees used the words "tricking users" and "deceptive UX." The people who built the system named what it was while they were building it.
Between 2021 and 2023, Hopper collected roughly $18 million in tip fees and $67.6 million in VIP support fees. That is $85.6 million pulled through a checkout screen most users never scrolled past.
Christopher Mufarrige, director of the FTC's Bureau of Consumer Protection, said it plain: Hopper showed people a total price that did not include hidden, pre-selected fees.
The settlement was $35 million. Less than half what they took in.
The Structural Flaw
The platitude treats transparency as a brand value. Something you claim. Something you put on the About page.
The problem is not that Hopper lacked a transparency claim. The problem is that the claim replaced a transparency system. The marketing page said one thing. The checkout screen did the other. The money followed the screen.
That is not an honesty problem. It is a design problem.
What to Build Instead
Transparency is a design choice you make at the point where money changes hands. Not a tagline. Not a value on a wall. A thing the checkout screen either does or does not do.
Once that is clear, three moves follow from it.
Move 1: Audit the transaction screen
Pull up every screen where a customer's card gets charged. List every pre-selected option, every fee below the fold, every toggle that defaults to "yes." If a customer can pay more than the listed price without choosing to add a cost, a default is doing your selling.
That audit takes less than an hour. What it asks of you is the will to look at what your own system does when no one is watching.
Move 2: Split the claim from the proof
Write down what your brand says about pricing, fees, or terms. Then open the real checkout flow and compare. The gap between the two is your exposure: legal exposure on paper, trust exposure in the repeat buyers who quietly stop coming.
Move 3: Test the default in reverse
Take one pre-selected upsell and flip it to unselected for 30 days. The drop is the share of your revenue that depends on a customer not paying attention. You get to decide what to do with that number, but you should know it before someone else finds it for you.
What the System Shows
Running this for one quarter does something the platitude never did:
You see which revenue lines depend on choice and which depend on inertia.
You find the gap between what your brand promises and what your checkout screen does.
You learn which customers chose you and which ones just did not scroll down.
Three Questions at the End of the Quarter
At the end of 90 days, ask three things.
→ Which revenue came from a clear "yes" and which came from a pre-selected default?
→ What looked like a pricing win but left no trace in repeat business?
→ Where did the checkout screen say something different from the sales page?
That is the difference between a brand that claims to be open and a system that proves it.

Where You Stand
Hopper's toggle collected $85.6 million. The marketing page collected trust it had not earned. The difference between a transparency claim and a transparency system is what the checkout screen does when the customer does not scroll. Now you know where to look.
