The 10 Longest A350 Routes!

The Airbus A350 is operated by 44 airlines, and as of October 2025, around 635 A350 aircraft are flying worldwide. The aircraft comes in two variants: A350-900 and A350-1000. Currently, 535 A350-900s are in active service, while airlines operate around 100 A350-1000s.

The A350 made its first flight in 2013. Airlines primarily use it on long-haul routes, replacing older and less fuel-efficient aircraft. Turkish Airlines (THY), our national flag carrier, operates 27 A350-900s and plans to add A350-1000s to its fleet next year.

The largest operator of the A350 is Singapore Airlines, with 65 aircraft. It is followed by Qatar Airways (58), Cathay Pacific (47), Delta Air Lines (35), Air France (34), Lufthansa (30), and Air China (30).

Many of these airlines also appear on the list of operators flying the longest A350 routes as of October 2025. Thanks to its ability to fly for many hours without refueling, the A350 has become the preferred long-haul aircraft for many carriers and the backbone of their wide-body fleets.

The model has become so popular that it has overtaken other long-haul aircraft such as the B767-300, B777-200, B777-300, and even the A330-200.

Passengers love the A350 as well—the aircraft consistently receives some of the highest customer satisfaction scores among all commercial aircraft in operation today.

With 435 orders for the A350-900 and 260 for the A350-1000, the aircraft is expected to play an even bigger role in commercial aviation in the years ahead.
