Airports: Commercial Aviation's Global Reach

Air travel is the most common method of travelling long distances, and there are over 40,000 airports around the world, according to various sources. However, only around 9,000 of these are served by commercial airlines. The United States has the most airports of any country, with over 13,000 listed with the Central Intelligence Agency.

London has 5 airports

London, the capital of the United Kingdom, is a major international city and a global hub for finance, culture, tourism, and more. As such, it is no surprise that London is served by several airports, connecting the city to the rest of the world. In fact, London has 5 airports, each with its own unique characteristics and serving different areas of the city.

The first airport to mention is London Heathrow Airport (LHR), which is the largest airport in London and one of the busiest in the world. Heathrow is located in the London Borough of Hillingdon and serves as the main gateway into the United Kingdom for international visitors. The airport has four terminals and two parallel runways, and it handles a significant portion of the UK's air traffic. Heathrow is well-connected to London and offers a range of transport options, including express train services and the London Underground.

The second airport is London Gatwick Airport (LGW), located in West Sussex. Gatwick is the second-busiest airport in the United Kingdom and is known for being a hub for low-cost carriers, with easyJet as the largest airline operating from this airport. Gatwick has two terminals and is easily accessible from London by train, with dedicated shuttle services to and from London Victoria.

London's third-busiest airport is London Stansted Airport (STN), located in Essex. Stansted is known for being a base for low-cost carriers, particularly Ryanair, which operates the majority of scheduled flights from this airport. Stansted also serves a wide range of European destinations and is easily accessible from Central London via the Stansted Express train service.

The fourth airport is London Luton Airport (LTN), located in Bedfordshire. Luton is another airport dominated by low-cost carriers, including easyJet, Ryanair, and Wizz Air. Luton is well-connected to London, with express train services and a people mover transit system connecting the airport to Luton Airport Parkway railway station.

Finally, there is London City Airport (LCY), the closest airport to Central London. Due to its location, the airport has a unique operating environment, with a short runway and a steep approach angle. As a result, only smaller aircraft are permitted to use the airport, and flight operations are limited to specific types of aircraft. London City Airport is a popular choice for business travellers and offers convenient connections to the financial district of London.

In addition to these five main airports, London is also served by several smaller airports and airfields, contributing to the city's busy aviation landscape.

The US has over 13,000 airports

The US has approximately 5,000 public-use airports, and around 14,400 private-use airports. Public-use airports are open to the public, while private-use airports are closed to the public. There are also heliports and seaplane bases included in these figures.

Airports are categorised by the type of activities they support. These categories include: commercial service, primary, cargo service, reliever, and general aviation. Commercial service airports are publicly-owned airports with at least 2,500 passenger boardings each calendar year and scheduled passenger service. Primary airports are commercial service airports with more than 10,000 passenger boardings each year. Cargo service airports are airports where only cargo is transported, with a total annual landed weight of over 100 million pounds. Reliever airports relieve congestion at commercial service airports, and general aviation airports are public-use airports with less than 2,500 annual passenger boardings.

The US has a large number of airports due to the important role they play in connecting communities to national and international markets, as well as promoting local economies. Airports also vary in size and the number of passengers served.

Brazil has over 4,000 airports

Of the over 4,000 airports, only around 500 are "real" airports open to the general public. The rest are private, often belonging to wealthy individuals. Brazil's farms are more isolated and larger than the average American farm, hence the need for landing strips. The country also has a lot of helipads.

Brazil's busiest airports include Congonhas Airport in São Paulo, which is known for having one of the shortest and busiest runways in the world. São Paulo, Rio de Janeiro, and Brasília are home to some of the busiest airports in the country and act as major hubs for domestic and international travel.

Brazil's vast network of airports makes it easy to visit interesting spots in the southern parts, smaller cities like Natal, and in the north of the country.
