All passengers entering the UK must clear Immigration at the first arrival airport point. You will be required to process through UK immigration & customs at this first UK airport. Please note: Passengers travelling onto another UK airport must have their duty free items in a sealed bag or they will be confiscated at security. This does mean that upon landing at your final destination you will arrive as a domestic passenger and will not be required to clear immigration for a second time. You will proceed immediately to collect your luggage or to the arrivals hall.
