A risk score for your flight — not just a price.
If the cheapest seat is all you want, you have a dozen tools for that. You’re here for a different question: will this flight actually get you there — on time, without a misconnect or a weather cancellation? That’s the whole game. It’s what we answer.
PlaneSane Score
Skyhaven 482 · JFK → LHR
One honest read on whether it gets you there.
7+ yrs of official data
decades of airport climate
is the layover realistic?
fair, not the headline
Sound like you?
A friend forwards a fare: “Lisbon, $380, on [airline].”
Good price. But is that airline dependable on that route? How does that airport handle weather in the month you’re flying? If you’re connecting, is the layover realistic? Those questions are the difference between a trip and a travel-day horror story — and they’re exactly the ones a booking site won’t answer.
You’re the kind of traveler who researches the airline, the route, and the weather before you book. PlaneSane is your home.
The score
One 0–100 read, built from the four things that actually decide your travel day.
On-time reliability
How this airline really performs on this route — 7+ years of official data, not reputation.
Weather risk
How your airports handle weather in your travel window — decades of climate plus a live forecast.
Connection safety
If you're connecting, is the layover realistic — or one delay from a misconnect?
Price
Shown, and sortable — but it's one input, never the thing that sets the score.
Each ring is the real thing — the same gauge you see on every result. We weigh them into a single PlaneSane Score, then rank your options by it.
Where the number comes from
A calibrated risk model — not a brand’s reputation, not a guess.
Official airline performance data. Foundation built on several years of certified, licensed, and authoritative data from verifiable public sources, with periodic refresh and expanding coverage.
Decades of airport weather. Historical climatology for thousands of airports worldwide, plus a near-term forecast for your specific travel window.
A forward-looking, calibrated model. We don't just average the past — we project the risk for the flight you're actually considering.
We’re a flight risk engine. We’re not a fare finder.
What PlaneSane is
- An honest read on the risk behind a flight or a whole itinerary.
- Even-handed: every airline is scored the same way, on the same data.
- Independent. No airline can pay to raise its score or its rank.
- Free to use — no account, no paywall on the score.
What PlaneSane isn’t
- A cheapest-fare booking engine — plenty of those already exist.
- Pay-to-play. A booking link never bends a score or a ranking.
- A guarantee. No tool can promise on-time; we give you the odds, honestly.
If you book through a link on PlaneSane, we may earn a referral — but it never changes a score, a ranking, or which flight we’d point you to. The scores come first; the links come after.
When we don’t know
If we can’t stand behind a number, we won’t show you one.
On-time reliability is the core of the PlaneSane Score. When we don’t yet have the on-time record for a route, we won’t fake a number from a network average — we tell you straight. You’ll still see the fares, the times, and the weather; you just won’t see a reliability score we can’t defend.
Not scored yet
No on-time history for this route. Fares, times, and weather are shown; reliability is withheld until we can score it honestly. Coverage keeps expanding.
Don’t take our word for it.
