Heathrow Airport Terminal 5

Terminal 5 is located at the western edge of the Heathrow area, between the north and south runways, and was opened nearly 19 years after its inception by Queen Elizabeth II. It was opened by Elizabeth on March 14, 2008. It opened to the public on 7 March 2008, and British Airways and its partner company Iberia have exclusive use of this terminal, which has 50 gates, 3 of which are hardstands. For two weeks after its opening, problems with the terminal's IT systems, combined with inadequate testing and staff training, disrupted operations, resulting in the cancellation of more than 500 flights. Until March 2012 Terminal 5 was used exclusively by British Airways as its global hub; However, due to the merger, on 25 March Iberia's operations at Heathrow moved to the terminal, making it the home of International Airlines Group. On July 7, 2020, it was moved to terminal 5 to allow easier connections from American's transatlantic flights to British Airways flights during the pandemic. However, all American flights except JFK returned to Terminal 3. However, Iberia moved its flights to Terminal 3 before it reopened due to the pandemic. China Southern Airlines is now using Terminal 5 due to the pandemic.

Built for £4.3 billion, the terminal consists of a four-storey main terminal building (Hall A) and two satellite buildings connected to the main terminal by an underground people transport system. Concourse A dedicated British Airways' narrow-body fleet for flights around the UK and the rest of Europe, with the first satellite (Concourse B) providing dedicated stands for BA and Iberia's wide-body fleet excluding the Airbus A380, and the second satellite (Concourse C) includes 7 special aircraft stands for A380. It became fully operational on June 1, 2011. Terminal 5 was named the 2014 Skytrax World's Best Airport Terminal at the Annual World Airport Awards.

The main terminal building (Hall A) has an area of ​​300,000 square meters (3,200,000 square feet), while Hall B covers 60,000 square meters (650,000 square feet). It has a capacity of 30 million passengers per year, as well as more than 100 shops and restaurants. It is also home to British Airways' Flagship lounge, the Concorde Room, as well as four British Airways branded lounges.

The transportation network around the airport was expanded to cope with the increase in passenger numbers. New branches of both the Heathrow Express and the Metro Piccadilly line serve a new shared Heathrow Terminal 5 station. A dedicated motorway spur connects the terminus to the M25 (between junctions 14 and 15). The terminal has a multi-storey car park with 3,800 spaces. A more remote long-term car park for business travelers is connected to the terminal by the Heathrow Pod, a personal rapid transit system that began operating in spring 2011. Within the terminal complex, an automated people mover (APM) system known as Transit is used to transport passengers between satellite buildings.
