    At check-in

    Save time, have your tickets and passport ready, and ensure your hand luggage contains only valuables and items you will need during the journey.

    Once you’ve checked your hold luggage and you got your boarding card , you may proceed to security control.

    Security Control

    All passengers must clear security control before entering the departure lounge at Heathrow.

    We advice to clear security control early to avoid any delay to your journey.

    Please check with your airline, some airlines impose limits on your hand baggage, and only limited quantities of liquid items can be carried through security control.

    For most destinations anything you buy after security control can be taken on to the aircraft – store staff will be able to advise you.

    Self-service check-in

    With self-service check-in you use a computer terminal to choose your seat and print your boarding card, and then you take your baggage to the bag-drop facility. If assistance is needed airlines staff are there to help you.
