The world’s longest flight: A 9,500-mile, 18-hour marvel of modern aviation
Advancements in aviation technology have revolutionised long-haul travel, enabling journeys once thought impossible. Among these is a non-stop flight between New York’s JFK airport and Singapore, operated by Singapore Airlines, which spans an astonishing 9,537 miles and lasts 18 hours and 40 minutes. This feat represents the pinnacle of modern aviation engineering and passenger service.
Breaking long-haul records
When people think of long-haul flights, the gruelling journey between the UK and Australia often comes to mind. While travelling to the other side of the globe is undoubtedly demanding, it usually requires stopovers in cities such as Dubai or Singapore, pushing the total travel time to around 23 hours.
However, with the advent of state-of-the-art aircraft, such as Singapore Airlines’ Airbus A350-900ULR, non-stop journeys of similar distances are now a reality. Launched in 2020, the route between JFK and Singapore is among the longest direct passenger flights in the world.
The aircraft behind the journey
The Airbus A350-900ULR (Ultra Long Range) has been specially designed for such mammoth journeys. Its modified fuel system allows for an additional 24,000 litres of fuel capacity without the need for extra tanks. This innovation enables the aircraft to cover the vast distance with ease.
The flight operates daily, departing JFK at approximately 11:30 pm and arriving in Singapore two days later at around 6 am. The return leg departs Singapore at 12:30 pm and lands in New York around 6 pm the following day. To maximise efficiency, these flights follow the “great-circle route,” a path near the North Pole that provides the shortest distance between two points on the globe. Alternatively, the jetstream route may be utilised to save time and fuel.
Passenger comfort and culinary excellence
Given the length of the flight, passenger comfort is paramount. The aircraft is configured with two classes – business and premium economy – ensuring an elevated travel experience for all passengers.
Singapore Airlines has paid meticulous attention to meal timing and composition to help passengers adjust to the extended journey. Antony McNeil, the airline’s food and beverage director, explained to USA Today Travel:
“The intention is that within three hours of departing, you’ve already started your first meal service. Then six or seven hours later, the crew will come back, so midflight you’re eating quite a large meal. The meals are designed to help you feel fuller for longer, so you’re not looking for snacks.”
The meals, included in the ticket price, are tailored for the ultra-long-haul experience. Economy dishes range from fried beef in oyster sauce with egg noodles to paneer korma with basmati rice. Complimentary alcoholic and non-alcoholic beverages are also offered.
A record-breaking journey
While Singapore Airlines’ JFK-Singapore route is among the longest continuous flights, it is not the absolute record-holder. That title belongs to a historic flight by a Cessna 172 in the late 1950s, which remained airborne for an astonishing 64 days, 22 hours, and 19 minutes.
Additionally, the longest scheduled passenger flight was Air Tahiti Nui’s Boeing 787-9 journey from Tahiti to Paris in 2020, covering 9,765 miles in 16 hours and 20 minutes. This exceptional route was temporarily operated due to pandemic restrictions, which made stopovers impractical.
The future of ultra-long-haul travel
The mantle of the world’s longest flight is set to change hands again in 2026. Australian airline Qantas is developing its ambitious “Project Sunrise,” a non-stop service linking Sydney with New York and London. These flights are expected to last up to 20 hours, pushing the boundaries of aviation even further.
As technology evolves, the possibilities for long-haul travel continue to expand, transforming the way people experience global connectivity. For now, Singapore Airlines’ 18-hour journey remains a marvel, embodying the very best of modern aviation.
