Enter a 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, or through security in good time.
Airport trips fail in the same two ways: you leave far too early and lose an hour to a car park, or you leave too late and someone is stood at a kerb — or missing a flight. Leave By fixes both with one number. Enter a flight and where you're driving from, and it tells you the minute to walk out of the door.
Both directions follow the flight live, so a delay moves your leave-by time with it. Both use real drive times rather than a guess at the distance. And once you're on the road, the "I'm driving" mode re-routes from your GPS and tells you whether you're still on schedule.
Four inputs, all adjustable, and no account needed to change any of them:
Free, no sign-up, and installable as an app. Start with an airport pickup or a departing flight.
It tells you the exact time to leave for the airport. Track an arriving flight and it works forwards from the landing time through baggage reclaim to when your passenger reaches the kerb. Track a departing flight and it works backwards from the departure time through check-in and security. Either way it adds your live drive time and tells you when to walk out of the door.
Use the arrivals/departures toggle at the top of the page. There are also dedicated pages for each: the airport pickup timer and the departure timer, which remember which mode they are in.
Allow 20 minutes from landing for a domestic hand-luggage arrival and up to 45 for a large international one, then add your drive. Leave By combines the live landing time, the airport allowance and the drive so you reach the kerb as they clear baggage.
Allow about 60 minutes at the airport for a domestic flight with hand luggage, 90 with checked bags, and 2 hours for an international one, then add your drive and a get-ready cushion. Leave By works this out from your flight's live departure time.
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.
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.
