Air transport in the United Kingdom is the commercial carriage of passengers, freight and mail by aircraft, both within the United Kingdom (UK) and between the UK and the rest of the world. In the past 25 years the industry has seen continuous growth, and the demand for passenger air travel in particular is forecast to increase from the current level of 236 million passengers to 465 million in 2030. One airport, London Heathrow Airport, is amongst the top ten busiest airports in the world. More than half of all passengers travelling by air in the UK currently travel via the five London area airports. Outside of London, Manchester Airport is by far the largest and busiest of the remaining airports, acting as a hub for the 20 million or so people who live within a two-hour drive. Regional ai
