The Wright brothers’ first powered flight in December 1903 covered just 120 feet (36.6 meters). Fast-forward 123 years to July 2026, when an Airbus A350-1000ULR reportedly flew an extraordinary 14,338 miles (23,076 kilometers) from Melbourne, Australia, to Toulouse, France, on a test flight. That’s almost 630,000 times the distance of the Wright brothers’ pioneering flight. In just over a century, aviation has progressed from a few seconds in the air to journeys spanning entire continents without a single stop. And that’s the beauty of aviation. No matter how far apart people are, it brings them closer together, with some nonstop flights between the United States and Asia now lasting almost 19 hours.

However, when ranking the world’s longest flights, distance is not always as straightforward as it seems. Published figures vary by measurement method and rounding; for example, Newark–Singapore is reported at anywhere between 9,484 and 9,534 miles. With Qantas’‘ Project Sunriseset to push the boundaries of nonstop commercial aviation even further, ultra-long-haul services such as Houston–Sydney and New York–Auckland are often included in these rankings. In this article, however, they are excluded because their destinations are in Oceania, and this piece focuses only on Asia.

Philippine Airlines operates one of the world’s longest nonstop flights, connecting New York’s John F. Kennedy International Airport (JFK) with Manila’s Ninoy Aquino International Airport (MNL). Covering approximately 8,520 miles (13,712 kilometers), the journey takes around 17 hours and 20 minutes aboard the airline’s Airbus A350-1000, Philippine Airlines’ newest aircraft.

Demand for international travel to and from Manila continues to grow. Between January and April 2026, the airport handled 8,831,746 international passengers, an increase of 6.9% compared with the same period in 2025. International aircraft movements grew even faster, rising by 8.9% to 41,692 departures and arrivals. This growth reflects Manila’s growing importance as an international aviation hub and the opportunities it offers Philippine Airlines to strengthen its long-haul network.

To meet growing demand, Philippine Airlines announced additional nonstop services to Vancouver, Toronto and New York for November and December 2026. The carrier plans to increase its Manila–New York frequency from three to four weekly flights beginning December 2, providing additional passenger and cargo capacity. The expansion forms part of the airline’s broader fleet and network strategy. As PAL President Richard Nuttall explained, North America remains one of the airline’s most important markets.

Connecting two of the world’s leading technology hubs, Air India’s nonstop service between San Francisco International Airport (SFO) and Bengaluru’s Kempegowda International Airport (BLR) covers approximately 8,700 miles (14,000 kilometers). Often described as the ‘Silicon Valley Express’, flight AI176 took about 17 hours and 51 minutes to link California’s technology industry with Bengaluru, widely regarded as India’s Silicon Valley. The route was historically operated using the Boeing 777-200LR, with the Boeing 777-300ER also deployed.

The service operated three times weekly on a seasonal basis, alternating between nonstop flights from San Francisco to Bengaluru with an onward connection to Kolkata (CCU) and nonstop flights from Kolkata to Bengaluru. By bypassing traditional connecting hubs such as Dubai, Doha, and Singapore, Air India offered passengers a more direct connection between the two technology centers. However, operating such a long route presented considerable challenges, particularly in terms of fuel consumption, operating costs, and airspace restrictions.

Despite its strategic importance, Air India suspended the nonstop San Francisco–Bengaluru service from March 1, 2026, reportedly due to rising operating costs and airspace constraints. Although its seasonal nature leaves open the possibility of a future return, no confirmed resumption has been announced. For now, passengers traveling between the two cities must rely on connecting services, including Air India’s flights via Delhi. The route remains an example of how even strong demand between major international markets does not always guarantee the commercial viability of ultra-long-haul operations, especially after persistent maintenance issues, even resulting in the deaths of 242 people. However, one airline’s withdrawal could create an opportunity for another. Industry rumors suggest that United Airlines is considering new ultra-long-haul services from San Francisco to India, particularly Delhi (DEL) and Bengaluru (BLR). While these plans remain unconfirmed, they could potentially restore nonstop connectivity between Silicon Valley and India’s technology capital.

Los Angeles – Singapore

Approximately 8,770 miles

Singapore Airlines operates one of the world’s longest nonstop routes between Los Angeles International Airport (LAX) and Singapore Changi Airport (SIN). Covering about 8,770 miles (14,114 kilometers), flights SQ35 and SQ37 take about 16 hours and 25 minutes, depending on direction and prevailing winds. The route is operated using the Airbus A350-900ULR, a specially adapted version of the A350-900 designed for ultra-long-haul operations.

The A350-900ULR has increased fuel capacity and an extended range, allowing Singapore Airlines to fly such long journeys without a stop. Interestingly, the aircraft has no standard Economy or First Class cabin, offering only Business Class and Premium Economy. This configuration reduces passenger numbers and helps manage aircraft weight while providing greater comfort on flights lasting more than 16 hours. Depending on weather conditions and prevailing winds, flights may take a westward route across the Pacific or follow a more northerly path over the Aleutian Islands and Japan before continuing towards Singapore.

The route also highlights the growing importance of nonstop connectivity between the US West Coast and Southeast Asia. While Singapore Airlines currently dominates this ultra-long-haul market, competition could eventually increase. Industry speculation suggests that American Airlines may be considering launching its own nonstop service between Los Angeles and Singapore. Although no official plans have been confirmed, such a move would introduce competition on a route where the combination of aircraft capabilities, premium demand, and operational efficiency plays a crucial role.

Newark – Singapore

Approximately 9,534 miles

Singapore Airlines operates one of the world’s longest nonstop flights between Newark Liberty International Airport (EWR) and Singapore Changi Airport (SIN), covering approximately 9,534 miles (15,343 kilometers). Newark’s strategic location within the New York metropolitan area makes the service particularly attractive to business travelers from New Jersey and Manhattan. Interestingly, Singapore Airlines operates two exceptionally long nonstop routes serving the same metropolitan market, with its other service departing from New York’s John F. Kennedy International Airport (JFK) — see below.

The route is operated using the Airbus A350-900ULR, an aircraft specifically designed for ultra-long-haul operations. Its lightweight composite structure, advanced aerodynamics, and efficient engines help reduce fuel consumption. Singapore Airlines also deliberately removed conventional Economy Class from its A350-900ULR aircraft, offering only Business Class and Premium Economy. This configuration reduces aircraft weight while allowing the airline to generate higher revenue per passenger, helping make such demanding flights commercially viable.

However, this is not Singapore Airlines’ first attempt at connecting Newark and Singapore nonstop. The airline originally launched the route in 2004 using the Airbus A340-500, but discontinued it in 2013 as the aircraft’s high fuel consumption made the service increasingly expensive to operate. The introduction of the more efficient A350-900ULR allowed Singapore Airlines to revive the route in October 2018, demonstrating how advances in aircraft technology can transform the economics of ultra-long-haul flying.

New York-JFK – Singapore

Approximately 9,537 miles

Taking the top spot is Singapore Airlines’ flight SQ23 from New York’s John F. Kennedy International Airport (JFK) to Singapore Changi Airport (SIN). Covering approximately 9,537 miles (15,349 kilometers), it is the world’s longest scheduled nonstop commercial passenger route by great-circle distance. Operated daily using the Airbus A350-900ULR, the journey is scheduled to take around 18 hours and 55 minutes, though actual flight times vary with weather and routing and average about 17 hours and 54 minutes.

The flight typically travels across Europe, the Middle East and India before reaching Singapore. Now, it follows a route across Europe and parts of Central and South Asia, including Türkiye, Azerbaijan, Turkmenistan, Afghanistan and Pakistan, before continuing to Singapore via India. Due to prevailing winds, the westbound journey generally takes longer than the eastbound return service, SQ24, despite covering the same distance. With such a long journey, Singapore Airlines has prioritized passenger comfort and premium demand over maximizing capacity. The A350-900ULR offers only Business Class and Premium Economy, with no standard Economy Class cabin. Given the time zone difference and late-night departure, passengers on SQ23 arrive in Singapore two calendar days after leaving New York.

While Singapore Airlines currently holds the record, its position could soon be challenged. Qantas’ Project Sunrise aims to introduce nonstop flights between Sydney and London Heathrow in October 2027, covering approximately 10,500 miles (17,000 kilometers) in around 20 hours. The service is expected to become the world’s longest scheduled commercial flight, surpassing Singapore Airlines’ New York routes. More than a century after the Wright brothers’ first powered flight, the next milestone in ultra-long-haul aviation is already approaching.
