Some of the world’s longest nonstop international flights from the United States now stretch well beyond 15 hours, linking American hubs directly with Southeast Asia, Australia, and the South Pacific. At the top end of the list in 2026 are routes such as Singapore Airlines’ nonstop flights from New York to Singapore, alongside ultra-long-haul services from carriers including Qantas, Air New Zealand, United, and Philippine Airlines. Route rankings and mileage figures in this article are based on Cirium Diio schedule data.

What makes these flights especially interesting is that they are not all built around the same model. Some rely on specialized aircraft like the Airbus A350-900ULR, while others use the Boeing 787-9, Airbus A350-1000, or even the Airbus A380 to connect city pairs that once required a stop. Together, they show how airlines are using a mix of aircraft types, hub strategies, and premium-heavy cabins to make some of the longest nonstop routes in the world work from the US.

New York-JFK – Manila

7,400 nautical miles

At number seven is Philippine Airlines’ nonstop link between New York-JFK and Manila, which stretches about 7,400 nautical miles and remains one of the longest regularly scheduled international flights from the United States in 2026. The route is operated by the Airbus A350-1000. The current schedule shows PR127 leaving JFK at 1:45 AM and arriving in Manila at 6:25 AM the next day, while the westbound PR126 departs Manila at 7:25 PM and reaches New York at 11:20 PM the same day. The scheduled block time is about 16 hours 40 minutes from JFK to Manila and 15 hours 55 minutes from Manila to JFK.

This route already had a notable history before the A350-1000 arrived. Philippine Airlines resumed New York service in 2015 with a Vancouver stop, ending a 17-year absence from the New York market, and then upgraded the flight to full nonstop service in October 2018 using the Airbus A350-900. That 2018 launch was significant because it created the airline’s first true nonstop connection between Manila and New York and gave the Philippines a much more direct link to the US East Coast.

What makes the flight especially interesting in 2026 is that it has now become one of the first major showcases for Philippine Airlines’ new flagship. Airbus says the carrier’s A350-1000s seat 382 passengers in a three-class layout, and the aircraft is intended to support long-haul expansion across North America. That makes JFK-Manila more than just a very long flight. It is also a route that traces Philippine Airlines’ broader long-haul evolution, from one-stop service, to A350-900 nonstop flying, to a larger and newer A350-1000 now taking over one of the airline’s most important transpacific missions.

Dallas/Fort Worth – Sydney

7,450 nautical miles

At number six is Qantas’ Dallas/Fort Worth to Sydney nonstop, which covers about 7,450 nautical miles. The route is operated by the Airbus A380, giving Qantas one of the most capacity-heavy aircraft on any flight this long from the US. Based on Qantas’ filed schedule, the block time is about 17 hours 25 minutes from DFW to Sydney and 15 hours 25 minutes from Sydney to DFW, a gap largely explained by prevailing winds that make the US-to-Australia sector longer.

The route also has a long history within Qantas’ North American network. Qantas launched Sydney to Dallas/Fort Worth in 2011, initially with the Boeing 747-400, using DFW as a major gateway for onward American Airlines connections across the United States. The airline later upgraded the service to the A380, giving the route a much larger premium cabin and more overall capacity, though the aircraft type has varied at times depending on operational needs.

What makes the flight notable is not just its length, but its role in Qantas’ long-haul strategy. Dallas is not simply another US destination for the airline. It is one of Qantas’ most important American gateways because of its partnership ties and its position deep in the US domestic network. Using the A380 on such a long sector shows that the route is designed not only for range, but also for heavy demand, strong premium traffic, and broad connecting flows on both ends of the Pacific.

Houston – Sydney

7,640 nautical miles

At number five is United Airlines’ Houston Intercontinental to Sydney nonstop, which spans about 7,460 nautical miles and is operated by the Boeing 787-9 Dreamliner. Schedule data for 2026 shows the flight blocked at roughly 17 hours 30 minutes from Houston to Sydney and about 15 hours and 45 minutes from Sydney to Houston.

The route has been important to United for several years because it gave the airline a direct Australia link from one of its biggest inland hubs rather than from a West Coast gateway. United first launched Houston-Sydney in 2018, using the route to connect not just Texas but also a broad swath of the central and eastern United States to Australia over a single stop-free flight. That made it a different kind of Pacific service from United’s San Francisco and Los Angeles operations, which are more naturally positioned for transpacific flying.

What stands out most is how much the route depends on the 787-9’s balance of range and efficiency. Houston is far enough inland that a nonstop to Sydney becomes a serious ultra-long-haul mission, yet the market is still strong enough to support direct service. That makes IAH-SYD a good example of what the Dreamliner was designed to do: connect distant city pairs that would have been much harder to serve profitably with older long-haul aircraft.

4

Los Angeles – Singapore

7,600 nautical miles

At number four is Singapore Airlines’ Los Angeles to Singapore nonstop, which stretches about 7,600 nautical miles and is operated in 2026 by the Airbus A350-900. Schedule data shows the flight blocked at about 16 hours 20 minutes from Los Angeles to Singapore and 15 hours 30 minutes from Singapore to Los Angeles, keeping it firmly among the longest international flights from the United States this year.

What makes the route especially interesting is that Los Angeles has been part of Singapore Airlines’ network for decades, but not always as a nonstop. Singapore Airlines’ own history notes that it launched Los Angeles via Tokyo with the Boeing 747-300 in 1983, which shows how long the market has mattered to the carrier. For many years, Los Angeles was served as a one-stop route rather than a nonstop one, reflecting the limits of earlier aircraft and the economics of ultra-long-haul flying at the time.

The nonstop version is a much newer chapter in that story. Singapore Airlines announced in 2018 that it would launch nonstop Los Angeles service on November 2, 2018, restoring a direct link between the two cities after years of one-stop operations. That makes LAX-SIN a good example of how a long-established route can evolve over time: first as a tag-on service via another Asian gateway, then later as a true nonstop made possible by newer-generation aircraft and changing market conditions.

3

Auckland – New York-JFK

7,650 nautical miles

At number three is Auckland to New York JFK, a sector of about 7,650 nautical miles that is unusual in this ranking because it is served by two airlines, both with the Boeing 787-9. Air New Zealand operates the route nonstop as its own standalone service, with its schedule showing a flight time of about 16 hours 15 minutes from Auckland to New York and 17 hours 35 minutes from New York to Auckland. Qantas also serves the same transpacific sector, but as part of its Sydney-Auckland-New York routing on the 787-9, giving the Auckland-JFK leg a second operator even though the Australian carrier is really using it as an intermediate segment on a longer Australia-US service.

The two airlines arrived at the route from different directions. Air New Zealand launched Auckland-JFK in September 2022, presenting it as a landmark nonstop link between New Zealand and New York and one of the longest flights in its network. Qantas, by contrast, uses Auckland as the stop on its New York service from Sydney. That also reflects a longer history in Qantas’ New York strategy, because before today’s Auckland routing, the airline had long served New York via Los Angeles using the Boeing 747.

The route is also interesting because it sits in the shadow of Project Sunrise. Qantas has made clear that Project Sunrise is designed to enable nonstop flights from Australia’s east coast to New York and London, using specially configured Airbus A350s. When those flights arrive, they will reduce the need for Qantas to route New York service via Auckland.

Dallas – Melbourne

7,800 nautical miles

At number two is Qantas’ Dallas/Fort Worth to Melbourne route, which spans about 7,800 nautical miles and is operated by the Boeing 787-9. When Qantas first detailed the service, it said the flight would be blocked at about 15 hours 45 minutes from Melbourne to Dallas/Fort Worth and 17 hours 35 minutes from Dallas/Fort Worth to Melbourne.

The route itself is a relatively new part of Qantas’ US network. Qantas launched Melbourne-Dallas/Fort Worth in December 2022, giving Melbourne its own nonstop link to the American hub rather than relying only on Sydney for deep US connectivity. That mattered because Dallas is not just another US destination for Qantas. It is one of the airline’s most strategically useful gateways thanks to the breadth of onward connections available through American Airlines, Qantas’ close transpacific partner.

That partnership is a big part of why Dallas keeps appearing in Qantas’ network strategy. The airline has long emphasized the strength of DFW as an American hub, and that logic helped underpin earlier Qantas service from Sydney to Dallas/Fort Worth as well. Melbourne’s addition extended that same model to a second Australian gateway, allowing Qantas to funnel passengers into American’s huge domestic network while also giving US travelers another one-stop option to Australia beyond the West Coast gateways. On a route this long, the 787-9 is doing more than simply flying far. It is supporting one of the most strategically important alliance flows across the Pacific.

New York-JFK & Newark – Singapore

8,250 nautical miles

At number one are Singapore Airlines’ nonstop flights from both New York JFK and Newark to Singapore, each stretching about 8,250 nautical miles and operated by the Airbus A350-900ULR. The scheduled block time is roughly 18 hours 40 minutes from New York JFK to Singapore and 18 hours 30 minutes from Singapore to JFK, while the Newark to Singapore service is blocked at about 18 hours 45 minutes eastbound and 18 hours 25 minutes westbound. These flights sit at the very top of the US ultra-long-haul market in 2026, and they are also among the clearest examples of an airline tailoring an aircraft to one very specific mission.

What makes the aircraft especially notable is its cabin layout. Singapore Airlines configured the A350-900ULR in just two classes, with 67 Business Class seats and 94 Premium Economy seats, leaving standard economy out entirely. That reflects the economics of flights this long, where the carrier is prioritizing higher-yield traffic and a less dense cabin over maximum seat count.

These nonstop services are also part of a much longer New York story for Singapore Airlines. The carrier previously operated Singapore-Newark nonstop with the Airbus A340-500 beginning in 2004, which at the time set a new record for the world’s longest commercial flight. It also served New York-JFK via Frankfurt.
