The UK's most popular airport, and also one of the world's busiest, London Heathrow is always a hive of activity, with flights leaving to worldwide destinations at all times of day and night.
Around a hundred airlines fly out of Heathrow, offering flights to over two hundred cities across the globe, a major undertaking by anyone's standards. Reflecting how busy the airport is, the number of travellers going through London Heathrow annually is in the region of 65 million. For a relatively small country such as the UK this really is a stupendous number, and really brings home how important Heathrow is in the realms of international travel and also just how well organised the airport must be to turn around all these people and get them on their way on time.
