Flight connections with British Airways at London Heathrow

The flight connections process within Heathrow airport will vary depending on your origin and final destination. When you arrive at Heathrow, please follow the purple ‘Flight Connections’ signs (as shown to the right), which will lead you to your next flight.

We recommend that you allow the following minimum connection times:

  • 60 – 70 minutes for connections within the same Heathrow terminal.
  • 90 minutes for connections that require travel between terminals at Heathrow.

You must be at the gate for your onward journey at least 20 minutes before your connecting flight departs, so please ensure you allow plenty of time, for example if you need to collect your bags or require additional support getting through the airport.

London Heathrow flight connections - FAQs

collapsedshowWhich gate is my flight departing from?

Please check the information screens at regular intervals and make sure that you’re at the gate no later than 20 minutes before the flight departs so you don't miss your flight.

Gate information at Heathrow airport becomes available shortly before the flight opens. 

If your flight departs from Terminal 5, please be aware that this terminal is made up of three buildings: the main terminal building (A Gates) and two separate satellite buildings (B Gates and C Gates) connected by a transit train.

Please wait in the main terminal (A Gates) until your gate is announced. It takes approximately 20 minutes to get to B Gates or C Gates so please always ensure your flight is displayed on the screens before leaving the main terminal. Then please follow the signs to the transit train or use the moving walkway that offers easy escalator/lift access. The journey time is the same for either option.

If you use the British Airways app you will receive gate notifications directly on your mobile.

collapsedshowDo I need to collect my bags?

If your baggage tag shows your final destination you can rest assured your bags will be forwarded on automatically to your connecting flight.

If it shows 'LHR', 'LGW' or 'LON', please follow the yellow signs for 'Arrivals/Baggage reclaim' to collect your bags and check it in again as normal for your connecting flight. You will also need to collect all your bags if you're connecting to/from London Heathrow, Gatwick, London City or Stansted.

If you're not sure, please ask a member of staff when you check your bags in.

collapsedshowCan I leave the airport?

If you have less than six hours until your flight departs, we strongly recommend that you wait at the airport. If you choose to leave, you will need to pass through passport control (and Customs if applicable). Please note that it is your responsibility to ensure you have all the appropriate documents required to enter the UK.

When you return to the airport, you must check in again as normal for your connecting flight, pass through airport security and be at the boarding gate at least 20 minutes before the scheduled departure time of your flight.

collapsedshowCan I meet someone who’s transferring flights?

Unfortunately it's not possible for you to go through customs and passport control to meet the person transferring flights unless you’re also checked-in for a flight leaving that airport terminal that day.

However, the person travelling can exit through "Arrivals" to meet you, or leave the airport if they have enough transfer time between flights (more than 6 hours for Heathrow and Gatwick) and the necessary documentation to enter the UK. Please note that it is always the traveller's own responsibility to check their passport and visa requirements for each airport/country in their itinerary.

When the person travelling returns to the airport they will need to go through the usual security checks, including a full screening of their hand baggage because they are re-entering the airport. The liquids and hand baggage restrictions for that airport will apply.

collapsedshowWhere can I leave my bags?

For security reasons there are no storage lockers for baggage at the airport.

Left baggage services are operated by the Excess Baggage Company at Heathrow and Gatwick and are only available to customers arriving into the UK, i.e. you will need to pass through passport control (and customs if applicable) and then check in again as normal for your connecting flight.

There are also left luggage facilities at London City and Stansted airports once you’ve cleared passport control and customs.

collapsedshowWhat if I miss my connecting flight?

If you miss your connecting flight at London Heathrow, please go to the British Airways Customer Service desk in the Flight Connections area to rebook.

At other London airports, please speak to a member of the British Airways Customer Service team.

collapsedshowWhat happens with the liquids I buy at the airport or on board?

If you buy any liquid, gel or cream products of more than 100ml at a Duty Free shop or on board, you may carry them through Security to your connecting flight provided the items and the receipt are sealed inside a Security Tamper Evident Bag at the point of purchase. If you buy items on board, please ask cabin crew to do this for you.

If necessary, Security will reseal items in a new bag. We cannot accept liability for any products opened or confiscated during transit or disembarkation.

Please keep in mind that any items you buy at the airport or on board count towards your hand baggage allowance for your next flight. If you exceed this, you may need to check the items in and be charged a fee.

collapsedshowWhat happens if my baggage is lost, delayed or damaged?
