London City Airport in the context of "Heathrow Airport"

Heathrow Airport (IATA: LHR, ICAO: EGLL), also known as London Heathrow Airport and named London Airport until 1966, is the primary and largest international airport serving England and the United Kingdom. It is the largest of the six international airports in the London airport system (the others being Gatwick, Stansted, Luton, City and Southend).

The airport is owned and operated by Heathrow Airport Holdings. In 2024, Heathrow was the busiest airport in Europe, the fifth-busiest airport in the world by passenger traffic and the second-busiest airport in the world by international passenger traffic. Heathrow was the airport with the most international connections in the world in 2024.

The Docklands Light Railway (DLR) is an automated light metro system primarily serving the redeveloped Docklands area of London and providing a direct connection between London's two major financial districts, Canary Wharf and the City of London. First opened on 31 August 1987, the DLR has been extended multiple times, giving a total route length of 38 km (24 miles). Lines now reach north to Stratford, south to Lewisham, west to Tower Gateway and Bank in the City of London financial district, and east to Beckton, London City Airport and Woolwich Arsenal. An extension to Thamesmead is currently being proposed.

Normal operations are automated, so there is minimal staffing on the 149 trains (which have no driving cabs) and at major interchange stations; the four below-ground stations are staffed, to comply with health and safety regulations for underground stations. The DLR was one of the first major railway infrastructure projects in Britain where access for disabled people was considered, with level access into the train from platforms and lifts at all stations.

The Metropolitan Police Service (MPS), commonly known as the Metropolitan Police, Met Police, or the "Met", is the territorial police force responsible for law enforcement and crime prevention within Greater London. In addition, it is responsible for specialised tasks throughout the United Kingdom, such as dealing with counter-terrorism throughout the UK, and the protection of certain individuals, including the monarch, royal family, governmental officials, and other designated figures. It is also referred to as an eponym as "Scotland Yard" or "the Yard", after the location of its original headquarters in Great Scotland Yard, Whitehall, in the 19th century. The Met is presently headquartered at New Scotland Yard, on the Victoria Embankment.

The main geographical area covered by the Met, the Metropolitan Police District, consists of the 32 London boroughs, and excludes the square mile of the City of London – a largely non-residential and financial district, overseen by the City of London Police. As the force responsible for the majority of the UK's capital, the Met has significant responsibilities and unique challenges, such as protecting 164 foreign embassies and High Commissions, policing London City and Heathrow airports, protecting the Palace of Westminster, and managing a higher volume of protests and events than any other British police force, with 3,500 such events in 2016.
