Stansted Airport: London's third-largest airport, located in Essex, with one terminal
Stansted Airport, located in Essex, is London's third-busiest airport. It is situated 42 miles (64km or 68km) northeast of Central London, near Stansted Mountfitchet, Uttlesford. Stansted Airport has one terminal building, with the Stansted Airport railway station situated directly below the main concourse.
The airport is a base for several European low-cost carriers, including being the largest base for Ryanair, serving over 150 destinations. It is also used by private companies such as Harrods Aviation, Titan Airways, and XJet terminals, which handle private flights, charter flights, and state visits. Stansted is the fourth-busiest airport in the United Kingdom, after Heathrow, Gatwick, and Manchester.
The history of Stansted Airport dates back to the post-World War II era, when British cargo airline London Aero and Motor Services began operations there in 1946. The Ministry of Civil Aviation took control of the airport in 1949, and it was used by various UK charter airlines. The US military returned in 1954 to extend the runway for a possible transfer to NATO, which ultimately did not occur, and the airport remained in civil use.
In the 1960s, Stansted was considered as a potential site for London's third airport, but it was not initially selected. However, in 1979, the Conservative government chose Stansted for long-term development, and redevelopment plans were approved in 1985. The airport was acquired by the Manchester Airports Group in 2013 for £1.5 billion, and an £80 million terminal redevelopment programme was launched.
Travelling to and from Stansted Airport, the Stansted Express train service is the quickest way to reach Central London, with a journey time of 47 minutes to London Liverpool Street. There are also coach services available, such as National Express and Airport Bus Express, which offer routes to major train and Tube stations in London.

London City Airport: a small airport closest to central London, with a single runway
London is served by six international airports and several smaller airports, making it the busiest airport system in the world by passenger numbers. London City Airport (IATA: LCY, ICAO: EGLC) is one of the six major London airports, along with London Gatwick, London Heathrow, London Luton, London Stansted, and London Southend. London City Airport is the closest airport to central London, located just 9.5km (6 miles) east of central London and 4.8km (3 miles) from Canary Wharf. It is situated in the Royal Docks in the Borough of Newham, about 6 miles (10 kilometres) east of the City of London. The airport is easily accessible by Tube, bus, taxi, or train, with its own London City Airport DLR station on a branch of the Docklands Light Railway. The Docklands Light Railway is the UK's first fully accessible railway for wheelchair users, with step-free access and designated wheelchair areas on all trains.
London City Airport is a relatively small airport, covering an area of about 60 hectares (150 acres) as of 2020. It has a single runway, which is 1,508 metres (4,948 feet) long, and a steep approach at a 5.5° angle (compared to the usual 3 degrees). Due to its size and the short length of its runway, only multi-engine, fixed-wing aircraft up to Embraer E195-E2, Airbus A220, and A318 size are allowed to operate at the airport. The airport also has strict noise limitations and other restrictions, which further limit the types of aircraft that can use it.
The airport was first proposed in 1981 by Reg Ward, the Chief Executive of the London Docklands Development Corporation (LDDC), and developed by the engineering company Mowlem between 1986 and 1987. The airport site initially covered 37 hectares (92 acres) and the first aircraft landed on 31 May 1987, with the first commercial services operating from 26 October 1987. Queen Elizabeth II officially opened London City Airport in November 1987. In its first full year of operation in 1988, the airport handled 133,000 passengers, with the earliest scheduled flights to and from Plymouth, Paris, Amsterdam, and Rotterdam.
Over the years, London City Airport has expanded and passenger numbers have grown significantly. By 1995, passenger numbers reached half a million, and in 2005, the airport was purchased by a consortium comprising insurer AIG Financial Products and Global Infrastructure Partners (GIP). In 2016, it was bought by a Canadian-led consortium of AIMCo, OMERS, the Ontario Teachers' Pension Plan, and Wren House Infrastructure Management of the Kuwait Investment Authority. As of 2019, the airport handled 5.1 million passenger movements, making it the fifth-busiest airport in the London area after Heathrow, Gatwick, Stansted, and Luton.
