Why this exists
Every connection raises the same three questions — will I make it, can I leave the airport, what do I do with the hours — and the answers are scattered across forum threads, decade-old blog posts and airline fine print. LayoverStamp puts them in one place, computed for your exact case: airport, layover length, ticket type, passport, and time of day.
How verdicts are computed
Each airport carries three curated numbers: an indicative minimum international connection time, a realistic minimum layover for leaving the airport (immigration both ways, distance to the city, and a 90-minute buffer to re-clear security), and city transit time. The checker adds a ~90-minute penalty for separate-ticket itineraries, because collecting and rechecking bags — with no airline protection if your first leg is late — is the single most underestimated risk in air travel. Verdicts are graded from DO NOT BOOK through COMFORTABLE based on your spare time beyond those minimums.
Important honesty: minimum connection times legally vary by airline, alliance, terminal pair and season. Our figures are the practical baseline for planning; your airline's published MCT for your specific itinerary is the binding number.
The verification promise
Travel data rots. Visa schemes change, quiet rooms close, terminals reshuffle. Every airport page displays the date its facts were last verified, and re-verification is treated as the core work of this site, not an afterthought. If you spot something stale or wrong, we want to know — corrections ship fast and the verified date updates when they do.
The Layover Oracle
The Oracle is an AI assistant powered by the Anthropic API, scoped strictly to layover questions. Its answers are grounded in the same verified per-airport dataset that powers the checker — when a question involves an airport we don't cover, it says so rather than guessing. It always reminds users to verify visa matters with official sources.
What LayoverStamp is not
Not immigration advice, not legal advice, and not a guarantee that any connection will be made. Visa and entry notes cover a verified set of passports per airport — the checker tells you plainly when yours is not yet in that set. Always verify entry requirements with official government sources and confirm connection rules with your airline before booking or relying on a plan.
Affiliate disclosure
Some links on this site — lounge passes, airport hotels, travel insurance, tours and eSIMs — are affiliate links. They cost you nothing and fund the ongoing verification work. Placement is need-driven: we link a product where the tool has just identified the need for it, and we don't rank or recommend anything because of commission. If a product isn't worth it for the layover in question, we say so.
