Terminal 3 was opened as the Oceanic Terminal on 13 November 1961; it was built to handle flight departures for long-haul routes. Renamed Terminal 3 in 1968, it was expanded in 1970 with the addition of an arrivals building. Other facilities added included the UK's first moving walkways. BOAC and the two US airlines,
Pan American World Airways and
Trans World Airlines (TWA), dominated operations at the terminal throughout the 1960s and 1970s. In 1969 the terminal was renovated to handle the new
Boeing 747 which was introduced to the airport on 23 January 1970. In 1990 Pan American sold its Heathrow landing rights to
United Airlines around the same time TWA sold them to
American Airlines. The terminal was refurbished between 1987 and 1990 at a cost of £110 million. In 2006, the new £105 million Pier 6 was completed to accommodate the
Airbus A380 superjumbo; Emirates and Qantas now operate regular flights from Terminal 3 using the Airbus A380. Redevelopment of Terminal 3's forecourt through the addition of a new four-lane drop-off area and a large pedestrianised plaza, complete with canopy to the front of the terminal building, was completed in 2007. These improvements were intended to improve passengers' experiences, reduce traffic congestion and improve security. As part of this project, Virgin Atlantic was assigned its own dedicated check-in area, known as 'Zone A', which features a large sculpture and atrium. As of 2013, Terminal 3 has an area of . Heathrow Airport Limited also has plans for a £1 billion upgrade of the rest of the terminal over the next ten years which will include the renovation of aircraft piers and the arrivals forecourt. A new baggage system connecting to Terminal 5 (for British Airways connections) is currently under construction. In addition to the baggage system, the baggage claim hall is also set to undergo changes with dedicated A380 belts and an improved design and layout. In 2020 due to the
COVID-19 pandemic, all flights from Terminal 3 and 4 were suspended and flights temporarily moved to Terminals 2 and 5. The railway and tube station remained open to serve Terminal 2. The terminal was reopened for use by Virgin Atlantic and Delta on 15 July 2021. ==Usage==
