Enter an inbound flight and where you're driving from. It works out when to walk out the door so you're at the kerb as they clear baggage — not an hour early, not late.
Picking someone up is a guessing game: leave too early and you circle the terminal for an hour; leave too late and they're stood at the kerb with their bags. Leave By removes the guesswork. Enter the inbound flight number and where you're driving from, and it works out the exact minute to walk out the door so you arrive just as they clear baggage.
The leave-by time is built from four things: the flight's landing time (live, and it follows delays), how long it takes to get through the airport, your drive with traffic, and a small get-ready cushion. Each is adjustable, and once you're on the road the live "I'm driving" mode re-routes from your GPS and shows whether you'll beat them to the kerb.
The gap between wheels-down and your passenger actually walking out of arrivals is the part most people underestimate. As a rough guide:
Leave By defaults to 40 minutes for this and lets you dial it in per trip. When in doubt, it's better to be waiting in the cell-phone lot than to have your passenger stood at the kerb — so pad international pickups generously, and let the live flight tracking absorb any delay.
Dropping someone off instead? Use the departures timer, which works backwards from the departure time through check-in and security.
It depends on the flight's landing time, how long it takes to get through the airport (typically 20 minutes for a domestic hand-luggage arrival and up to 45 for a large international one), and your drive. Leave By combines all three and gives you the exact time to leave so you reach the kerb as they clear baggage.
From wheels-down to walking out is usually 20 to 45 minutes: taxiing to the gate, immigration, and baggage reclaim. Leave By defaults to 40 minutes and lets you adjust it with a slider.
Yes. With live traffic enabled it uses real-time driving times; otherwise it applies an adjustable traffic allowance on top of the free-flowing drive estimate.
Leave By uses live flight data and follows delays, updating your leave-by time automatically. It is a planning aid, so always sanity-check against the airport's live arrivals board.
No. Leave By is free and needs no sign-up. It runs in your browser and can be installed as an app for one-tap access.
