What to Do When Landing in the UK
Follow the Arrival sign if you are ending your journey in London or transferring to another flight within the UK. You must have your passport and any necessary visa ready for checking. Go downstairs to collect your baggage; free trolleys are available for your bags. Clear Customs by taking the Red Channel if you have anything to declare and the Green Channel if you have no goods to declare. You will then be in the Arrival Hall for transport into London or transfer to domestic flights.
UK and USA Flags
The Union Jack is the name of the British flag. It consists of three crosses: of England, Scotland and Ireland. The jack used to be the name of the flag which was hung from the back of a ship.
Uncle Sam is the nickname for the federal government or the typical citizen of the USA. It arose in the neighborhood of New York about 1812, as a colloquial way of reading the initials US, frequently used on government supplies to the army.
