About Slipstream
An AI travel optimiser for people who have points and would rather not study airline loyalty programmes to use them well.
Every existing tool in this space assumes you already understand transfer partners, award charts and alliances. Slipstream assumes you don't — and shouldn't have to. You tell us what you have and where you want to go, in plain English, and we answer one question: what is the smartest thing you can do with your points today?
Honest by design
Our recommendations are computed, not guessed, and every one shows its working: the points, the taxes, the cash a seat would cost, and the resulting value per point. We don't rank options by who pays us. Where we earn affiliate commission — on flight searches, hotels, parking and the like — it never changes which redemption we say is best.
Where the data comes from
Transfer ratios (cited to Amex UK's partner page), which airlines fly which routes (cited to the source pages) and airport data are curated reference data. Award prices: Our own estimate from flight distance — not published award charts or live seats. Taxes also reflect our estimate of each airline's surcharge level. Live award availability and pricing aren't integrated yet — when they are, they'll come from licensed providers. Until a number is confirmed against the airline, treat it as a well-informed estimate — and always verify before transferring points.
