Singapore Airlines is the world’s largest operator of the Airbus A350, with a total of 65 in its fleet. From its hub at Singapore Changi Airport (SIN), the Star Alliance carrier deploys its fleet of A350s to more than 45 destinations across the world, taking advantage of the aircraft’s impressive fuel efficiency to expand its long-haul reach while maintaining its exceptional customer service standards and onboard passenger experience.
In this article, we will use data from Cirium, an aviation analytics company, to explore Singapore Airlines’ longest nonstop routes operated by the Airbus A350 in 2025. We will also look at the aircraft’s role in the carrier’s wider fleet and operation, and the different A350 variants it operates..
The World’s Longest Nonstop Commercial Flight
Singapore Airlines’ longest nonstop route operated by the A350 is between the carrier’s hub at Singapore Changi Airport (SIN) and John F. Kennedy International Airport (JFK). At 9,487 miles long, this is not only the longest nonstop route in Singapore Airlines’ extensive route network, it is also the longest nonstop commercial flight in the world. In 2025, the Star Alliance carrier is scheduled to operate a total of 365 flights in each direction, equating to one flight per day.
The second-longest nonstop route operated by Singapore Airlines’ fleet of A350s is just three miles shorter. The carriers’ route between Singapore Changi Airport (SIN) and Newark Liberty International Airport (EWR) is 9,484 miles long, and is also operated daily throughout 2025.
Singapore Airlines’ flights to both New York-JFK and Newark are operated by the carrier’s specially configured A350-900ULRs. These aircraft were built to have an additional fuel tank, ensuring that enough fuel is available for the ultra-long-haul routes. The carrier also equips its A350-900ULRs with only two classes of travel – business class and premium economy, meaning that there is no economy class cabin on these aircraft, helping to reduce the weight of the aircraft and improving comfort for those onboard at the same time.
When Singapore Airlines took delivery of its first A350-900ULR, the carrier’s CEO at the time, Goh Choon Phong, celebrated the new arrival.
“This is a proud moment for both Singapore Airlines and Airbus, not only because we have again strengthened our partnership, but also because we have pushed the limits with this highly advanced new aircraft to extend long‑range flying to new lengths.”
The US West Coast
For Singapore Airlines’ next-longest nonstop route operated by the A350, we move over the US West Coast. In third place is the carrier’s service between Singapore Changi Airport (SIN) and Los Angeles International Airport (LAX), which is 8,758 miles long. In 2025, Singapore Airlines is due to operate a total of 521 flights in each direction on this route.
Next up is Singapore Airlines’ nonstop service to San Francisco International Airport (SFO), which is the carrier’s long-haul A350 route with the highest frequency. This route is 8,440 miles long, and the carrier has a total of 730 flights scheduled in each direction in 2025. Singapore Airlines goes head-to-head with fellow Star Alliance member, United Airlines, which deploys its Boeing 787-9s on the route.
Rounding off Singapore Airlines’ presence on the US West Coast is its fifth-longest A350 route, which operates between Singapore Changi Airport (SIN) and Seattle-Tacoma International Airport (SEA). This route comes in at 8,068 miles long, and is due to be operated 240 times in each direction in 2025.
Over To Europe
Continuing the list of Singapore Airlines’ longest nonstop Airbus A350 routes, we move over to Europe, with the carrier’s sixth-longest service being between its hub at Singapore Changi Airport (SIN) and Manchester Airport (MAN) in the UK. This route is 6,810 miles long and is due to be flown a total of 260 times this year.
This route previously continued on to Houston George Bush Intercontinental Airport (IAH), with Singapore Airlines benefiting from fifth-freedom rights to transport passengers solely between Manchester and Houston. However, the Houston tag-on was discontinued in April 2025, reportedly due to low demand and poor yields, allowing Singapore Airlines to redeploy its aircraft on other, more profitable routes.
The next-longest nonstop route operated by the A350 is between Singapore Changi Airport (SIN) and Barcelona El Prat Airport (BCN) in Spain, which is 6,776 miles long. In 2025, Singapore Airlines plans to operate 136 nonstop services between the two cities, but the carrier also serves Barcelona with additional one-stop services via Milan Malpensa Airport (MXP) in Italy up to five times per week.
The route between Singapore Changi Airport (SIN) and London Gatwick Airport (LGW) is the carrier’s eighth-longest nonstop route operated by the A350, at 6,758 miles long. The Star Alliance carrier also serves London Heathrow Airport (LHR) four times per day with a mix of A380 and Boeing 777-300ER aircraft. Although Singapore Airlines is the only carrier linking Singapore directly with London Gatwick, the carrier goes head-to-head with both British Airways and Qantas on its services to and from London Heathrow.
Rounding Out The Top Ten
Its ninth-longest nonstop A350 route is to Paris Charles de Gaulle Airport (CDG), which covers a distance of 6,666 miles. This is one of two daily services operated by the carrier between Singapore and the French capital, deploying its Boeing 777-300ERs on the other. Singapore Airlines goes head-to-head with Air France on the route, which operates up to two flights per day with a mix of 787-9 and 777-300ER aircraft.
Rounding out the top ten of Singapore Airlines’ longest nonstop A350 routes is the carrier’s service to Brussels Airport (BRU) in Belgium, which is a total of 6,561 miles long. The airline previously served Brussels until 2003 when the SARS outbreak brought an end to the route. After a more than 20-year hiatus, delayed once more by the COVID-19 pandemic, the carrier resumed this route in April 2024. In addition to linking the two cities, Singapore Airlines has also extended its codeshare agreement with Brussels Airlines, providing passengers with ample connection opportunities across Europe and beyond.
Singapore Airlines & The Airbus A350
Singapore Airlines took delivery of its first A350-900 back in March 2016 and its first A350-900ULR in September 2018. The carrier’s first long-haul route to be operated by the A350-900 was to Amsterdam Schiphol Airport (AMS), while Kuala Lumpur International Airport (KUL) was the aircraft’s first short-haul destination at the carrier.
The latest data from ch-aviation shows that today, the carrier operates a total of 65 A350s, making it the largest operator of the aircraft, ahead of Qatar Airways with 58 and Cathay Pacific with 48.
Its fleet of A350s consists of two variants: 58 A350-900s and seven A350-900ULRs. The passenger capacity of each variant is outlined in the table below:
