Multimodal trip planning
Most travel tools plan one leg well and leave you to staple the rest together. This is how we plan the whole door-to-door journey instead — and where the honest limits are.
A flight search answers one question: how do I get from one airport to another. A multimodal plan answers the real one: how do I get from my front door to the key of my room, using whatever combination of transport makes that journey calm and affordable.
For a trip from the United States to Western Europe or the Mediterranean, that usually means five or six different kinds of movement in a row — a ride to the airport, a long-haul flight, an airport train, a high-speed rail leg, sometimes a ferry, then a short transfer at the far end. Each one has its own timetable, its own price and its own way of going wrong.
Any one leg is easy to look up. The difficulty is the seam between two legs: whether 55 minutes is enough after an international arrival with bags and immigration, whether the last ferry of the day waits for a delayed train, whether a terminal change eats the connection you thought you had.
We compare every join against the buffer that type of transfer genuinely needs, then say plainly whether it holds, is tight, or breaks. A connection that is tight is labelled tight — we never quietly rank it first because it looks fast.
Plans fall apart on cost as often as on timing, because the airfare is only part of what the journey costs. We add the ride or the parking, the airport access ticket, the flight and its taxes, the rail or ferry fare, the transfer, the stay and the city tax, and present one complete-trip total calculated the same way every time.
Where a figure comes from a live provider response we say so. Where it is our own estimate from sample inventory, we label it an estimate. No hidden fees, and no number that changes quietly between the moment you decide and the moment you pay.
Travelling with children, grandparents, or a group spread across several households changes the buffers, not just the head count. Luggage takes longer. Connections you would sprint alone are connections you miss as five. Children's ages matter for fares and for seating rules.
So we take the ages, apply longer realistic buffers to group transfers, and rank options with that in mind — which is why the calm option and the fast option are often not the same plan.
A multimodal trip is a chain, so one delay is never just one delay. From three days before departure we watch the flights you entered and, when an airline reports a change, we show it on your trip page along with the later legs it puts at risk.
Alerts are in-app today and can be up to an hour behind the airline. That is the honest limit, and we would rather say it than imply real-time certainty we do not have.
The numbers come from a deterministic engine, never from a language model. Routes, schedules, prices, travel times, connection feasibility and ranking are calculated the same way every time and can be re-checked. Our assistant exists to explain that output in plain language — it is not allowed to invent a price, a seat, a review or a departure.
Tell us where you're leaving from, where you're going and who is travelling. You'll get ranked door-to-door options with every leg timed, every cost counted and every connection scored.
