Due to great distances flown, these flights are operated via great circle route or the polar route. The longest ultra long-haul flights as of May 2007 are operated between Southeast Asia and North America.
Following are few dynamic factors determining the non-stop time of a commercial passenger jet.
Historically in the modern jet era, Israel's El Al set the first significant non-stop record times for both long haul flights, and later on in 1990's, ultra-long haul service. In June 1961, the longest long-haul passenger flight between Tel Aviv and New York on a Boeing 707 completed its journey in 9 hours and 33 minutes (9,137 km - 5,677 mi - 4,934 nm).
In May 1975, Iran Air began its non-stop, scheduled service between Tehran-New York using its newly acquired long-range Boeing 747SP's, completing the journey in 12 hours and 15 minutes, an absolute record for both flight time and distance (9,867 km - 6,131 mi - 5,328 nm). Although the airline's plans for its non-stop Tehran-Los Angeles flight never materialized due to the Islamic revolution in 1979, such flight would have made a leap in the time and distance records (12,222 km - 7,595 mi - 6,599 nm). Coincidentally, the Tehran-New York flight route was suspended in November 1979.
In April 1976, Pan Am set a new record for non-stop, long-haul flights with its New York-Tokyo route (10,854 km - 6,745 mi - 5,861 nm). In December of that year, the airline set yet another new record for the longest non-stop flight with its Sydney-San Francisco service, covering 11,937 km (7,417 mi - 6,445 nm) in distance. Both routes were operated by Boeing 747SP.
In the 1980s, Cathay Pacific began non-stop long-haul flights between Hong Kong to Vancouver with a Boeing 747-200 classic. While these flights were not the longest routes at the time, they were the first non-stop flights between Asia and North America (excluding Alaska).
In modern day aviation, Singapore Airlines introduced ultra long-haul flights on 3 February 2004 to Los Angeles and on 28 June 2004 to Newark and currently these two flights hold the record for the longest commercial passenger non-stop flights in the world based on both time and distance. The route from New York City (JFK or Newark) to Hong Kong is the longest non-stop route in the world to have more than one daily flight, and to be served by more than one airline. The route between New York and Mumbai has the maximum number of airlines operating non-stop flights in the ultra long-haul category.
The following table lists the world's longest non-stop scheduled passenger routes in distance order. City-pairs may be served utilising different routings on the return journey, which may therefore involve different route lengths. Different weather conditions, particularly the direction of jet streams, also have a significant impact on the time needed to complete the journey. For example, Singapore Airline's flight 22 from Singapore to Newark follows a 15,700km great circle route, while its return flight flight 21 is a 16,600km polar route over the north pole. The Singapore - Los Angeles route takes about 16 hours to complete, but takes about 18.5 hours on the return trip.

The Boeing 777-200LR airliner can cover the distance between antipodes when devoid of payload, but its range decreases significantly with the added weight of cargo and passengers. As of 2007, no airline has plans to introduce a non-stop service longer than the Singapore-Newark run, though both Airbus and Boeing have hinted at interest in developing variants to their long-haul airliners to make a London-Sydney nonstop flight economically feasible, for which purpose the Airbus consortium will offer the special A350-900R XWB variant to British Airways.
On 10 December 2005 a Boeing 777-200LR dubbed the Worldliner completed the world's longest non-stop passenger flight traveling 13,422 miles or 21,602 kilometers eastwards (as opposed to normal westwards route for that sector which is twice shorter at 9647km) from Hong Kong to Heathrow, England in roughly 22 hours and 40 minutes. Onboard the 777-200LR were eight pilots including Suzanna Darcy-Hennemann, Boeing's first woman test pilot. Although the plane seats 301, there were only 27 passengers aboard this flight. They were a couple of Boeing executives; several Boeing 777 engineers; representatives from General Electric and a dozen journalists from around the world. This was not, however, the record for longest time staying aloft for an airliner. That record is held by a Trans World Airlines Lockheed 1649A Starliner on the inaugural London-San Francisco polar route on 1 October-2 October, 1957. The flight time was 23 hours and 19 minutes. The L-1649A was the last of the Constellation series, and the ultimate piston-engine airliner in terms of range and endurance.
