In modern day aviation, in August 1989, a Qantas Boeing 747-400 set a record for flying non-stop between Sydney and London at a distance of 18,001 kilometres (11,185 mi). However, this is only a delivery flight. This is followed more recently by Singapore Airlines introducing ultra long-haul flights on 3 February 2004 to Los Angeles, and on 28 June 2004 to Newark from Singapore Changi Airport (Flight SIA 22). These two flights held the record for the longest commercial passenger non-stop flights in the world based on both time and distance, until both routes were cancelled on October and November 2013, respectively. The route from New York City (JFK or Newark) to Hong Kong is the longest non-stop route in the world to be served by more than one airline (three daily non-stop and one via Vancouver by Cathay Pacific and 1 daily by United Airlines). The routes served between Los Angeles and Sydney have the maximum number of airlines operating non-stop flights in the ultra-long-haul category: 4 airlines—Delta Air Lines, Qantas, Virgin Australia, and United Airlines. In terms of flight frequency, Emirates tops the list of ultra-long-haul flight operators, Six flights operating from its Dubai base to Dallas/Fort Worth, Houston, Los Angeles, São Paulo, San Francisco, and Seattle. An ultra long-haul non-stop flight is a flight by a commercially operated airliner with: No scheduled intermediate stop of any kind A route length over 7,500 miles (12,100 km) These flights usually follow a great circle route, often passing over polar regions. As of February 2014, the longest non-stop scheduled airline flight only operates non-stop in one direction—from Australia to North America— and the return flight has a scheduled intermediate stop for refueling. However, this is the only ultra long-haul flight to operate as such, with all others being

Miles away London Heathrow Airport or Heathrow (IATA: LHR, ICAO: EGLL) is a major international airport serving London, England, known as London Airport from 1946 until 1965. Located in the London Borough of Hillingdon, in West London, Heathrow is the busiest airport in the United Kingdom and the third busiest airport in the world (as of 2012) in total passenger traffic, handling more international passengers than any other airport around the globe. It is also the busiest airport in Europe by passenger traffic and the third busiest by traffic movements, with a figure surpassed only by Charles de Gaulle Airport and Frankfurt Airport. Heathrow is London's main airport, having replaced RAF Northolt and the earlier Croydon Airport. The airport sustains 76,600 jobs directly and around 116,000 indirectly in the immediate area, and this, together with the large number of global corporations with offices close to the airport, makes Heathrow a modern aerotropolis which contributes an estimated 2.7% to London's total GVA. Along with the chosen cruising air speed, the time taken by a flight depends mainly on: The speed and direction of the winds at flight level, which can result in a tailwind, headwind, or crosswind at various points of the flight ATC route Flights crossing the middle latitudes often encounter the jet stream, which typically flows in a general eastward direction. As a result, flights traveling from west to east often experience a tailwind and have flight times that are considerably shorter than for flights traveling from east to west, which
The airport is owned and operated by Heathrow Airport Holdings, which also owns and operates three other UK airports, and is itself owned by FGP TopCo Limited, an international consortium led by the Spanish Ferrovial Group that includes Caisse de dépôt et placement du Québec and Government of Singapore Investment Corporation. Heathrow is the primary hub for British Airways and the primary operating base for Virgin Atlantic. Heathrow lies 12 nautical miles (22 km; 14 mi) west of Central London, and has two parallel east–west runways along with four operational terminals on a site that covers 12.14 square kilometres (4.69 sq mi). A consultation process for the building of a third runway and a sixth terminal began in November 2007, and the project was controversially approved on 15 January 2009 by Labour government ministers. It was subsequently cancelled on 12 May 2010 by the Cameron Government. The first phase of a new Terminal 2 complex which replaces the old terminal and adjacent Queen's Building is due to open in June 2014. The airport holds a Civil Aviation Authority Public Use Aerodrome Licence (Number P527), which allows flights for public transportation of passengers or for flying instruction In April 1976 Pan Am set a new record for longest non-stop scheduled flight with its New York–Tokyo route (10,854 kilometres (6,744 mi)). In December the airline set another record
