Flight prices have become notorious for their mood swings. A fare can sit at £100 on Monday, spike past £500 the next day, then quietly drop again hours later — same seat, same plane, wildly different price. It's the reality of how airlines re-price seats in response to demand in 2026, and it's left many travellers stuck in the tedious ritual of juggling browser tabs, shifting dates and second-guessing whether to book now or gamble on a delay.
RatePunk, a flight-deal app founded in 2020, wants to take that job off your hands. It's built a community of more than 370,000 members and holds a 4.6-star rating on the App Store worldwide. The premise is straightforward: the app scans roughly 150 million flight prices every day, calculates an average price for each route, tracks how fares have moved historically, and uses machine learning to spot when a price hits a genuine low. When a fare dips below what's typical for that route, you get an alert.
The feature that sets it apart is the AI Deal Score, which rates each fare out of 100 — but not on price alone. It factors in the airline and airport quality, departure and arrival times, the number and length of stopovers, and how the fare compares with that route's usual pricing. A score above 80 isn't just code for 'cheap'; it's an answer to the more useful question of whether a flight is actually good value once you look at the whole journey, not just the number on the ticket.
There are two ways to use it. The traditional route: pick a destination, set the app watching, and wait for a fare worth booking. Or flip it around — if you've got annual leave banked and no fixed idea where to go, you can browse whatever deals look good that day and let the destination choose itself. For anyone flexible on dates or open-minded about where they end up, that second mode is arguably the app's sweet spot.
Deals also come with context. Rather than just labelling something 'cheap', RatePunk shows how a fare stacks up against the route's average and price history, so you can see why it's been flagged. The app isn't promising every flight becomes a bargain — the point is to make good deals easier to spot and snap up without the mind-numbing comparison grind.
Who's it for? Travellers happy to be flexible. If you know exactly where you're going and exactly when, price-tracking tools will help less. But if you've got leave to use and either a flexible destination or flexible dates, RatePunk does the watching for you and hands you the verdict when something worthwhile appears. It's free to try, works on iOS and Android, and could save both money and a lot of tab-juggling.
