Reference excerpt

Heathrow Terminal 3 is an airport terminal at Heathrow Airport, serving London, the capital city of the United Kingdom. Terminal 3 is currently used as one of the main global hubs of the International Airlines Group members British Airways (alongside Terminal 5) and Iberia since 12 July 2022. It is also used by the majority of members of the Oneworld and a few SkyTeam alliances along with several long-haul non-affiliated airlines. It is also the base for Virgin Atlantic.

History

Terminal 3 was opened as the Oceanic Terminal on 13 November 1961; it was built to handle flight arrivals and 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 98,962 square metres (1,065,220 sq ft). 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

The main presence in Terminal 3 is Virgin Atlantic. American Airlines, British Airways, Cathay Pacific, Delta Air Lines, Emirates and Qantas are the other major users of the terminal. This terminal is mainly reserved for long-haul flights. British Airways and Finnair are the only short-haul airlines flying from this terminal. With the closure of Terminal 4 Air France and KLM operated from Terminal 3 during the downturn in traffic at the airport during the pandemic. Both airlines moved back to join their fellow SkyTeam members at the reopened Terminal 4 in March 2023.

Oneworld Terminal 3 is used by the majority of the members of the Oneworld airline alliance: American Airlines, Cathay Pacific, Finnair, Japan Airlines, Qantas, Royal Jordanian, and SriLankan Airlines. British Airways, which mainly uses Terminal 5, also offers some flights from this terminal. As of 12 July 2022, it is one of the global hubs of the International Airlines Group. However it is not used by Malaysia Airlines, Royal Air Maroc and Qatar Airways (all Terminal 4 only) or Iberia (Terminal 5 only).

SkyTeam Three SkyTeam member airlines use Terminal 3: Delta Air Lines, China Airlines and Virgin Atlantic. Delta moved all flights to Terminal 3 on 14 September 2016 to ease connections with partner Virgin Atlantic.

Non-aligned The principal non-aligned airline is Emirates. The other non-aligned airlines include Beijing Capital Airlines, Iran Air and LATAM Brasil. During the pandemic, new airlines Rwandair and Vistara began flights from this terminal. On 19 March 2024, Rwandair announced that it would operate flights to and from Terminal 4.

Star Alliance Today, no Star Alliance airlines use Terminal 3. Most Star Alliance airlines now use Terminal 2. In the past, a number of Star Alliance airlines used this terminal: Air Canada, Air China, Air India, All Nippon Airways, EgyptAir, Ethiopian Airlines, EVA Air, Scandinavian Airlines, Singapore Airlines, Thai Airways, and Turkish Airlines.

Ground transport

Inter-terminal transport Terminal 3 is connected by an underground walkway to Terminal 2. Terminals 4 and 5 can be reached by the free Elizabeth line or Heathrow Express rail service. London Underground services can also be used to transfer to Terminals 4 and 5 (the former requiring a change of train at Hatton Cross) free. In addition, numerous buses ply between the Central Bus Station (for Terminals 2 and 3) and the other terminals. However, using the train service is much quicker and easier for passengers with luggage.

Road links As one of the two central terminals at Heathrow, it is linked to the M4 motorway via the M4 spur road and through a tunnel under the north runway.

Rail links Terminal 3 is served by regular rail services from Heathrow Central and Heathrow Terminals 2 & 3 tube station. These stations, shared with Heathrow Terminal 2, are situated in the central terminal area and provide regular connections to other Heathrow terminals, to Central London, the London Underground network, and local destinations. As of 2022, services run from the early morning until approximately midnight.

Worked examples

Example 1 — a first encounter with Heathrow Terminal 3

Start with the simplest possible case. Write down what Heathrow Terminal 3 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Heathrow Terminal 3 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Heathrow Terminal 3 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Heathrow Terminal 3

In research: Heathrow Terminal 3 appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Heathrow Terminal 3 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Heathrow Terminal 3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 establishments in England, Airport terminals, Buildings and structures at Heathrow Airport, so understanding it makes those chapters shorter.
In everyday life: Look for Heathrow Terminal 3 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
