en.Wedoany.com Reported - The Boeing 787-9 has a maximum range of 8,705 miles (14,010 km), while the Airbus A330-900 has a maximum range of 8,438 miles (13,611 km), giving the former a 267-mile advantage. Both new-generation widebody aircraft are used for long-haul route operations, with airlines planning their global networks based on each model's characteristics.

The Boeing 787-9 boasts the longest range among all three 787 variants. Qantas deploys it on the direct route from Perth Airport (PER) to London Heathrow Airport (LHR), a flight launched in March 2018 as the first regular non-stop passenger service between the two countries. Qantas adjusted meal times for ultra-long-haul comfort and improved cabin humidity and lighting. The success of this route is a key driver for Qantas to advance its "Project Sunrise" initiative for even longer routes, which will connect other Australian cities with direct services to destinations in Europe and the United States.

The current longest route for the Airbus A330-900 is Delta Air Lines' direct service between its trans-Pacific hub at Seattle-Tacoma International Airport (SEA) and Taiwan Taoyuan International Airport (TPE), covering a distance of 6,074 miles.

The Boeing 787-9 completed its maiden flight in September 2013, with a structure comprising approximately 50% composite materials and powered by Rolls-Royce or General Electric engines. The design target was to reduce fuel consumption by about 20% compared to previous-generation aircraft of similar size. All Nippon Airways put the 787-9 into domestic service as the launch customer in August 2014, followed by Air New Zealand operating the first international commercial flight from Auckland Airport (AKL) to Sydney Airport (SYD) later that month. Depending on configuration, the 787-9 typically seats 250 to 300 passengers. The model has been introduced into the fleets of multiple airlines, including American Airlines and Riyadh Air.

The latest data shows United Airlines is the world's largest operator of the Boeing 787-9 with a fleet of 45 aircraft, closely followed by All Nippon Airways with 44. Riyadh Air has ordered 39 787-9s and expects to take delivery and expand operations from its hub at King Khalid International Airport (RUH) in Riyadh in the coming years.

The Airbus A330-900 is part of the A330neo (New Engine Option) program and made its first flight in October 2017. The model features upgraded Rolls-Royce Trent 7000 engines, A350-style wingtips, and the Airbus "Airspace" cabin interior. TAP Air Portugal deployed it as the launch customer in December 2018 on the route from Lisbon Airport (LIS) to São Paulo/Guarulhos International Airport (GRU). Depending on configuration, the A330-900 can seat 260 to 300 passengers and is used by airlines such as Delta Air Lines and Cebu Pacific for transatlantic routes, long-haul leisure services, and high-density regional flights.

Delta Air Lines is currently the world's largest operator of the Airbus A330-900 with a fleet of 39 aircraft, while TAP Air Portugal has 19. The largest outstanding orders come from VietJet Air (40 aircraft) and Cathay Pacific (30 aircraft), with Cathay Pacific planning to deploy them on Asia-Pacific routes from its hub at Hong Kong International Airport (HKG).

The Airbus A350-900 has a range of up to 9,300 miles (14,966 km), while the A350-900ULR can fly up to 11,000 miles non-stop. Singapore Airlines exclusively operates the A350-900ULR, flying the world's longest non-stop commercial flight from Singapore Changi Airport (SIN) to New York John F. Kennedy International Airport (JFK). Qantas plans to launch more direct flights between Australia and Europe and the United States next year using a fleet of Airbus A350-1000ULR aircraft equipped with extra fuel tanks, with ranges exceeding 10,000 miles (16,600 km).
