Hopper Promo Code 2026: $25 in Carrot Cash via Referral

Hopper stands out from all other travel comparators with its price-prediction algorithm: the app analyses billions of historical data points to tell you whether the current price of a flight or hotel is low, medium or high — and whether you should buy now or wait.

The interface shows a clear recommendation:

• "Buy now": the price is at its lowest, the chances of it rising are high
• "Wait": the price should drop in the coming days/weeks
• "Watch": Hopper will send you a push notification as soon as the price reaches the recommended level

Hopper estimates the algorithm's accuracy at around 95%. It's especially useful for long-haul flights where prices can vary 30 to 50% depending on when you buy. To compare several transport modes on a route, Omio aggregates train, bus and plane in one result.

Beyond the prediction algorithm, Hopper offers several premium features that go beyond a simple comparator:

Price Freeze: pay a few dollars ($5-20) to "freeze" the current price of a flight or hotel for 7 to 14 days. If the price rises, you still pay the frozen price. If it drops, you pay the lower price. Ideal if you're not yet sure you want to travel but fear the price will rise.

Price Drop Guarantee: if you bought a flight and the price drops within a certain window, Hopper refunds the difference in Carrot Cash. A guarantee that reduces the risk of buying "too early".

Flight disruption assistance: if your flight is cancelled or significantly delayed, Hopper offers automatic rebooking or compensation.

Carrot Cash is the most recurring discount on Hopper: credited by the referral and then by each booking, it stacks in your wallet and applies to your next booking. Note it expires after a period of inactivity (6 months without a booking, per Hopper), so use it before it lapses.

Hopper started as an app exclusively for flights, but has gradually expanded its catalogue:

✓ Flights: direct and connecting flights, all airlines, all destinations worldwide

✓ Hotels: more than 800,000 properties worldwide

✓ Car rentals: at airports and city centres

✓ Homes: apartment and house rentals (similar to Airbnb)

Hopper is particularly recognised for its strength on long-haul flights where the prediction algorithm generates the most significant savings. On Paris-New York, Paris-Tokyo or Paris-Montreal flights, the price difference depending on the purchase day can exceed €150-200 per person — and Hopper's algorithm helps identify the best moment.

On Hopper, savings don't come from a classic promo code but from two complementary mechanisms:

The referral credits $25 in Carrot Cash to a new member who signs up via an invite link (the referrer also gets $25). It's the best lever for a first booking and stacks with the best rate found by the algorithm.

Carrot Cash is then a recurring loyalty programme: you earn it automatically on every booking made via Hopper (flights, hotels, cars). It's stored in your wallet and deducted from your next booking. Unlike traditional miles, it has a direct euro/dollar value — but it expires after about 6 months of inactivity.

Hopper also runs occasional Carrot Cash bonuses (doubling during certain periods) — enable app notifications so you don't miss them.

The key question with Hopper: does the prediction algorithm really generate savings versus Booking, Expedia or Google Flights?

The nuanced answer: Hopper doesn't necessarily find lower prices in absolute terms than competitors at a given moment — it often finds the same prices. Its added value is in the timing of purchase: by telling you when to buy, it helps you avoid bad moments (weekends, the eve of holidays) and take advantage of price dips.

On long-haul flights (transatlantic, trans-pacific), the price difference depending on the purchase day can be very large and Hopper's algorithm is particularly effective. On last-minute hotels, Hopper is less differentiating — HotelTonight specialises in that niche with deals close to the date.

Hopper is the ideal app for flexible travellers who can afford to wait for the right time to buy. For urgent or last-minute bookings, its competitors are more suitable.

Hopper was founded in 2007 in Montreal and launched its consumer app in 2015. The app has more than 100 million downloads worldwide and has repeatedly been named "best travel app" by Apple and Google.

Strengths: a unique price-prediction algorithm, a simple, mobile-first interface, innovative Price Freeze to secure a price without buying immediately, recurring Carrot Cash, worldwide coverage of flights + hotels + cars.

Watch-outs: Hopper is exclusively a mobile app — you can't book from a computer. The premium features (Price Freeze, Price Drop Guarantee) are paid. Customer service can be harder to reach than a traditional OTA if there's a problem.

Hopper's welcome discount runs through its referral programme: it's limited to new accounts that have never booked, and triggers when you create the account via an invite link (or enter a referral code at sign-up). The $25 in Carrot Cash is credited on the first booking, and the referrer is credited once that booking is completed.

Accumulated Carrot Cash applies before payment confirmation, inside the app — it can't be added retroactively to an already-confirmed booking.

Key point: Carrot Cash expires after a period of inactivity (around 6 months without earning or spending it, per Hopper's terms; some promotional offers extend to 12 months). Check your balance regularly. Amounts and conditions vary by region and currency (around $25 in the US, ~€20 in the eurozone).

Hopper was founded in 2007 in Montreal by Frederic Lalonde and Joost Ouwerkerk. For several years, the company worked in stealth mode, building its price-analysis algorithm on billions of flight data points. The consumer app launched in 2015 and immediately went viral thanks to its promise of "telling you when to buy your plane ticket".

In 2019, Hopper raised $170 million to accelerate its development, then expanded its offer beyond flights: hotels (2019), car rentals and homes (2020-2021). The introduction of paid premium features (Price Freeze, Cancel for Any Reason) transformed the business model — Hopper now earns from these services as much as from booking commissions.

In recent years, Hopper has strengthened its Carrot Cash programme as a loyalty lever, with one-off bonuses and credit-card partnerships. We update this page regularly to guarantee the most recent Hopper promo codes.
