London welcomes millions of visitors each year, and for many, their first experience of the city begins at one of its major airports. From the world-renowned Heathrow to the convenient London City Airport, the capital is served by six airports, each with its own unique character and advantages.

Every tour of London will include a view of the Houses of Parliament and most guides conducting one will arrange for a stop so that people can take a photograph or selfie with Big Ben in the background. This provides the perfect souvenir of a visit to London.
