Why airlines choose Airbus A350 for world’s longest non-stop flights

To address ultra-long-haul markets, Airbus introduced the A350-900ULR (Ultra Long Range), capable of flying up to 9,700 NM—more than any other passenger aircraft currently in service. Modifications allow it to carry additional fuel without new tanks and support flights lasting over 20 hours. Singapore Airlines became the launch customer for this variant in 2018.

“This is a proud moment…because we have pushed the limits with this highly advanced new aircraft to extend long-range flying to new lengths. The A350-900ULR will bring more convenience and comfort to our customers and will enable us to operate ultra-long-range flights in a commercially viable manner. It will help us boost our network competitiveness and further grow the Singapore hub,” said Goh Choon Phong, CEO of Singapore Airlines.

Singapore Airlines uses its seven -900ULRs on nonstop services between Singapore and New York’s JFK and Newark Liberty International Airport. The cabin is configured with business class and premium economy seating only.

Airbus continues developing new variants such as the A350-1000ULR—designed for Qantas Airways’ “Project Sunrise” initiative targeting nonstop flights from Sydney or Melbourne to London or New York—and the dedicated freighter version, A350F. Qantas has ordered 12 A350-1000ULRs with four-class configurations including a wellbeing zone; entry into service is now expected by 2027 following flight testing.

Production data shows there are currently 645 active A350s worldwide: 528 are -900s, 97 are -1000s, and seven are -900ULRs. Major operators include Singapore Airlines (the largest overall operator), Qatar Airways (largest operator of the -1000), Air France, Delta Air Lines, Lufthansa, British Airways, Virgin Atlantic, Etihad Airways, and Cathay Pacific.

Airbus holds orders for both existing models and upcoming variants from airlines such as Turkish Airlines—which has committed to purchasing 61 A350-900s—as well as Air India, Korean Air, Riyadh Air, Emirates, United Airlines, Qantas and others. Recent commitments were announced at events like the Paris Air Show.

The manufacturer plans to increase production rates in response to strong demand; deliveries are sold out until at least 2031 with plans underway for potential future updates such as an “A350neo” featuring next-generation engines.

Since entering service—with Qatar Airways as launch customer on February 20, 2018—the A350 has been central in enabling airlines worldwide to operate some of their longest routes efficiently while maintaining passenger comfort.
