Honest review
Hopper is a real travel-booking company that started in Montreal and made its name as a mobile app. Book a hotel or flight through it and the reservation is genuine. What sets Hopper apart are its extras: it predicts whether a price will rise or fall and tells you to buy now or wait, it sells a paid "Price Freeze" that locks a price for a window, and it hands back "Carrot Cash" you can spend on future trips. The company is legitimate — most of the "is this a scam" noise online is about app-only support and the terms of those extras. Here's the honest breakdown.
We have no affiliate relationship with Hopper — this isn't a referral pitch. We surface a rate when it's the cheaper one, and only then.
A legitimate booking app with clever price tools — as long as you treat the prediction as timing advice, read the Price Freeze terms, and don't mistake Carrot Cash for a lower cash price.
Where Hopper is genuinely good
Where you should be careful
Hopper's headline feature is prediction: it looks at historical pricing for a route or hotel and tells you whether it expects the price to go up or down, with a "buy now" or "wait" recommendation. That's genuinely useful for timing a purchase — but it's a forecast about the future of one price on Hopper, not a check of whether the same room is already cheaper somewhere else today. Those are two different questions, and it's easy to read "buy now, price is about to rise" as "this is the best deal," when it only means "this particular price probably won't get better."
Price Freeze is an option you buy: pay a small fee and Hopper holds the current price for a set window, covering part of any increase up to a cap if the price rises before you book. It can pay off when prices really are volatile and you need time to decide — but the fee is gone if you don't book, and freezing a price is not the same as confirming it's the lowest one. Carrot Cash, meanwhile, is credit you earn to spend on future Hopper bookings; it's real value, but it's store credit locked inside Hopper, not money off the price you pay at checkout today.
Before you book a Hopper hotel, check three things
Hopper answers "is this price about to change?" What it doesn't answer is "is the exact same room cheaper on another site right now?" — and that's the question that actually decides whether you overpaid. To answer it you'd compare the specific hotel and dates against the property's own site and other booking sites, all-in after taxes and fees, and mentally strip out Carrot Cash since it's future credit, not cash off today. Doing that by hand across five tabs is tedious, which is exactly why most people trust the first price and the "buy now" nudge.
Underbook is a free Chrome extension that runs that comparison for you while you shop. On any named hotel it checks other booking sites for the same room and dates and shows the all-in totals side by side, so you can see whether the price in front of you — Hopper's prediction included — is really the lowest one before you commit. When it can't confirm two rooms match, it says so plainly instead of pretending. We earn nothing from Hopper; we just show the cheaper confirmed rate when there is one.
No. Hopper is an established travel-booking company and the hotel and flight reservations you make through it are real. The "scam" label usually comes from two things: support is mostly in-app chat, so resolving a change, cancellation, or refund can be slower and more frustrating than with a phone-line agency; and the paid extras — Price Freeze fees and Carrot Cash store credit — surprise people who didn't read the terms. That's friction and expectation-setting, not fraud. Understand the terms before you book and you avoid most of the complaints.
Sometimes — Hopper runs genuine app-only deals and its prediction can help you buy at a good moment. But its prediction is about whether that price will rise or fall over time, not about whether the same room is cheaper on another site right now. The only way to know you're getting the lowest price is to compare the exact hotel and dates across the property's own site and other booking sites, all-in after taxes and fees, and to treat any Carrot Cash as future credit rather than a discount on what you pay today.
It depends on the specific rate and fare you booked, just like any booking site — some are refundable, many discounted ones are not. The extra wrinkle with Hopper is that support runs mostly through in-app chat, so travelers sometimes find it slower to reach a person and resolve a cancellation or refund. Read the cancellation terms of the exact rate before you pay, and don't assume a deal is flexible just because the app made booking fast.
Carrot Cash is Hopper's in-app reward credit — you earn it through promotions or certain bookings and spend it on future trips booked inside Hopper. It's real value, but it's store credit, not cash back on the price you pay at checkout today, and it can only be used within Hopper. When you're comparing whether a Hopper deal beats another site, count the actual cash price and set the Carrot Cash aside, since you can't spend it anywhere else.
No. We have no affiliate relationship with Hopper. This page isn't a referral pitch — it's an honest answer to a question a lot of travelers ask. Underbook surfaces whichever site has the cheaper confirmed rate for your room, and shows the lower price even when it earns nothing from it.
A price prediction tells you the trend. Underbook compares the all-in price for your exact room across booking sites, so you can see whether the cheaper rate really is the same booking — right now, not someday. Free, and you always book where you choose.
