For more than 20 years, Singapore Airlines’ flight from New York’s JFK to Singapore’s Changi has been the longest nonstop flight in the world. More than 9,530 miles one way. No stops or refuels. Takeoff to touchdown clocks in at just under 19 hours.
In the not-so-distant past, this flight was something that didn’t seem like it could be a reality. Decades of innovations in fuel economy and engine efficiency made it possible. But something else—perhaps a smart combination of ergonomics and an attention to detail—has made for these flights not only an option for travelers, but an enjoyable experience. That is another feat altogether.
Over the years, Singapore Airlines has consistently had the longest flights in the world on its schedule. And during that time, it has innovated not only the flights, but the experience of flying itself.
In the US, average trip lengths are inching up, now averaging more than 500 miles per traveler. As long-haul flights get longer, and more ultra-long-range (ULR) flights (which are 16 hours or more) are being offered, being up at cruising altitude for half a day or longer is a reality for more travelers than ever before. To put this into perspective, it takes a spacecraft as little as four hours to reach the International Space Station.
Singapore Airlines has operated some of the longest flights in the world for more than two decades, and is celebrated for leading its engineering and production efforts on every flight path with comfort being top of mind.
Flights that operate with the A350-900 aircraft offer aisle access with every business class seat, which happens to be one of the widest seats in the sky and can easily convert into a full lie-flat bed. Every passenger has free access to unlimited in-flight Wi-Fi, and each seat has multiple charging ports, stowage spaces, and lighting options so flyers can easily work, sleep, or just relax with the in-flight entertainment.
Even the seats in Economy Class on certain aircraft have been engineered to allow for maximum personal space—not something often seen in main cabin seating. If the passenger seated in front of you reclines, the unique seat layout and ergonomic design in the Premium Economy Class allows everyone to keep their own individual space. Other seating design details in Premium Economy Class include calf rests, adjustable headrests, and armrests that aren’t shared between seats (so you get your own). It’s details like these that have cemented Singapore Airlines’ place as one of the world’s most-awarded airlines.
As technology—and what we know about air travel—changes, so do the airplanes themselves. New aircraft models are better suited for longer flights and ultra-long-haul routes because they are more fuel efficient. The Airbus A350-ULR, which is built with carbon fiber reinforced polymers, burns an average of 25 percent less fuel than older aircraft models and allows for improved air quality due to more optimized cabin altitude and humidity levels. Currently, Singapore Airlines is the largest operator of the A350, with 65 of the aircraft in its fleet, including seven A350-900ULRs. The A350-ULR plane is built specifically for ultra-long, nonstop flights, and has a longer flight range than any other aircraft capable of flying up to 9,700 nautical miles, or more than 20 hours nonstop. These planes are customized inside to optimize both fuel efficiency and travelers’ flight experiences, offering only Premium cabins, Business Class, and Premium Economy Class seats, so passengers have enough room to move, stretch out, and rest on flights that require it.
To continue improving the spaces travelers use while on their flights, Singapore Airlines recently announced an $800 million-plus cabin refurbishment program for 41 of its long-haul aircraft, due to be completed by 2030. The carrier is the only one to operate the A350-900ULR, with new design plans that include sliding doors to maximize square footage and privacy, as well as new, larger in-flight entertainment screens.
“Over the past six years, we have extensively engaged customers and stakeholders in the design of our next-generation long-haul cabin products, anticipating their evolving preferences and expectations down to the finest detail,” Singapore Airlines CEO Goh Choon Phong said. “The new First Class and Business Class seat designs will incorporate thoughtful elements that push the boundaries of comfort, luxury, and modernity, allowing our customers to relax or work effortlessly on board."
Upgrades aren’t just reserved for those traveling in Business Class and First Class, though. To ensure that every passenger embarking on their long-haul flights has access to these design upgrades, Singapore Airlines is also refreshing its Premium Economy Class and Economy Class cabins. The debut of the upgraded cabins will begin in 2026.
When airlines are operating ultra-long-haul routes with hundreds of customers on board, they face high demands for comfort, space, food and beverage, attention, and rest.
That’s why the most successful long-haul carriers invest so much in the configuration of their aircraft and crew training. Singapore Airlines’ cabin crew training program is 14 weeks long, compared to an industry average of six weeks. During this training period, as well as out in the field, cabin crew members are trained on how to best operate with the amenities and technologies of the specific aircraft to help customers make the most out of these features. That means intentionally planning meal times to help passengers’ bodies adjust to the time of the destination in an effort to help combat jetlag, or assisting with creating an account on KrisWorld, Singapore Airlines’ digital entertainment platform that allows customers to access more than 1,900 entertainment options prior to departure, and up to 30 days after they touch down at their destination.
Having a choice of in-flight entertainment or meal isn’t defined just as an availability of options on these long-haul flights, it’s a premium experience.
For those traveling in any of Singapore Airlines’ cabins aside from Economy Class, there’s an option to dine on the airline’s Book the Cook menu options. Each Book the Cook menu is handpicked by the Singapore Airlines International Culinary Panel, which includes multiple high-profile chefs—including French and Australian culinary tour de forces—and feature Wagyu beef, lobster, scallops, and even local veggies. To ensure the food you’re eating is nutritious as well as tasty, Singapore Airlines has employed some lesser-known production strategies to bring farm-fresh ingredients to in-flight meals. Grown on aeroponic farms, varieties of greens arrive on the plane shortly after harvest. Not only are these some of the freshest ingredients, but they are also responsibly grown. Aeroponic farming methods can grow the same amount of crops in a fraction of the space, require no pesticides, and use 95 percent less water than traditional farming methods.
Fresh ingredients that support your body and good health are becoming a mainstay for these long flights. After partnering with California’s renowned Golden Door in 2021, Singapore Airlines added more options to its menu, featuring dishes with ingredients that decrease inflammation, increase hydration, and prevent blood sugar spikes, like turmeric, blueberries, pumpkin, lentils, goji berries, and honey. Along with nourishing foods, Golden Door has also added well-being and exercise content to its in-flight entertainment to support customers’ entire day of travel.
With these innovative approaches, Singapore Airlines aims to take the lead in reimagining how we fly and reshaping the travel experience. Because travel begins the moment you board a plane—not when you arrive at the destination.
