    Passenger AmbassadorTransferring between flights at Heathrow? We aim to make your connection as simple and enjoyable as possible.

    For most connections* you won’t have to pick up baggage or check in for your departing flight, and if you’re connecting to an international flight you won’t have to clear passport control.

    Here’s your at-a-glance guide to Heathrow Flight Connections.

    Arriving at Heathrow

    Purple signsWelcome to London! Heathrow is a large airport but don’t worry – just follow the purple signs for Flight Connections.

    There are four terminals at Heathrow and you may need to transfer from one terminal to another. Just follow the purple signs to the coaching gates and hop on one of our regular, free transfer buses.

    Keep following the purple signs until you reach the departure lounge. At that point you’ll know how much time you have left to relax and enjoy the facilities without having to rush for your flight.

    Where to go

    Flight screenJust keep following the purple Flight Connections signs! If in doubt, don’t hesitate to ask one of our roaming Passenger Ambassadors for help. They’re airport experts and speak 39 languages between them. Just look for their purple uniforms.

    You can find the latest flight updates – along with terminal maps and a connection plan tailored to your journey – at Or, use the routing features of our smartphone app.

    Flight updates also appear on information screens in the terminal. Be aware that some flights operate under more than one airline's flight number – in that case the different numbers will be displayed in rotation.

    Things you’ll have to do

    Security officer


    Wherever you’re travelling from and to, you will need to pass through security and your hand baggage must be screened. It may help you avoid delays if you’re prepared.

    There are restrictions on liquids and sharp items, and you must remove laptops and tablets for separate screening. You’ll pass through a security archway so remove watches, coins and other metal items, and put them in a tray.
