Nine airlines currently operate the Airbus A350-1000, including Air Caraïbes, British Airways, Cathay Pacific, Ethiopian Airlines, Etihad Airways, French bee, Japan Airlines, Qatar Airways, and Virgin Atlantic. Among these carriers, all except Air Caraïbes use long-range equipment for flights to the United States.
The list of the ten longest A350-1000 flights from July to September includes both nonstop and one-stop services. These routes are ranked based on maximum block time during this period. Block time accounts for flight time, taxiing at airports, and short delays. It can vary due to factors like wind conditions or airspace restrictions.
According to Cirium Diio data, the longest route is Doha to Los Angeles International Airport with a block time of up to 17 hours and 5 minutes. This route is operated daily by Qatar Airways. Another route with the same block time is Ethiopian Airlines' Addis Ababa to Washington Dulles service. It operates four times weekly via Rome due to high elevation constraints in Addis Ababa.
