A flight-deal site that won't waste your time.
IoCarta is an error-fare detection service built in Antwerp, Belgium. We exist for one reason: to tell you when a flight is genuinely, provably mispriced, and to stay quiet the rest of the time.
Why most deal sites get it wrong
Most flight-deal newsletters work like this: they show a low number, label it a "deal," and assume you'll click. The trouble is, what counts as cheap depends entirely on the route. A €280 New York return is fantastic. A €280 Barcelona return is mediocre. Generic discount labels can't tell the difference, so they cry wolf, and you learn to ignore them.
How we find real error fares
IoCarta works from data, not guesswork. We continuously poll flight inventory across hundreds of routes from eight major European hubs (Brussels, Amsterdam, Paris, London, Frankfurt, Madrid, Barcelona and Rome) to more than 200 destinations worldwide.
Every price we see is stored in a rolling 60-day history. For each route, that history gives us a true median: what the flight actually costs over time, not what an airline wishes it cost. A fare only reaches our site if it sits 65% or more below its own route's median. Most days, that's just a handful of flights, and that is exactly the point. We don't pad the list to look busy.
Once a deal is live, we don't forget about it. Every active fare is re-checked against current prices every ten minutes. The moment it is no longer bookable, it comes off the site: no expired deals, no dead links.
How we make money
IoCarta is, and will remain, free to use. We earn a commission when you book through a partner link, and that never changes the price you pay. That is the entire business model. We don't sell your data, we don't run display ads, and we don't accept payment to feature a fare. If a deal is on IoCarta, it's because the maths said so.
Built for travelers who hate noise
No expired deals. No fake urgency. Just real prices, verified against real history.
