The Qatar Airways flight departed the Qatari capital of Doha in the morning and landed around 12:30 p.m. local time in Frankfurt, Germany. It marks the debut of the relatively lightweight, twin-aisle, long-range plane, which promises to connect smaller cities with major aviation hubs nonstop at a cheaper cost for airlines.
For passengers, the new plane offers wider panoramic windows and larger overhead storage space plus the ability to limit connections.
The A350 is the third — and final — major new aircraft in a decade. First there was the double-decker Airbus A380, which debuted in October 2007. It's the world's largest passenger jet, designed to carry up to 525 passengers between some of the largest cities on the planet.
Then came the lightweight Boeing 787, which carried its first passengers in October 2011. Thanks to its lower operating costs, the jet, marketed by Boeing as the Dreamliner, has led to new nonstop flights between cities that previously didn't have enough passengers to merit such service.
As with the Dreamliner, the A350's lightweight design allows it to burn significantly less fuel than other jets of similar size. A little more than half of the structure is made of composite materials such as plastic reinforced by carbon fibers. Add in titanium and advanced aluminum alloys and more than 70 per cent of the plane is made up of lightweight materials.
Airbus says the A350 will help open up nonstop routes like Shanghai to Boston, Massachusetts or Paris to Santiago, Chile.
The A350 can fly 276 to 369 passengers, depending on the variant and the airline's choice of seating configuration.
Qatar's version is fitted out with 36 business class seats that turn into fully flat beds and boast 17-inch TV screens, and an economy class section with 247 seats, with smaller TVs.
The state-backed airline has put considerable faith in the new model, with orders for 79 more planes. It received its first double-decker A380 from the European plane maker in September.
"The delivery of this new aircraft category into the Qatar Airways' fleet ... is a moment of absolute national pride for Qatar Airways and the state of Qatar," Qatar Airways CEO Akbar al-Baker said at an inauguration ceremony last week.
Qatar Airways' larger Gulf rival, the Dubai-based Emirates, also had plans to operate the A350. But it scrapped an order for 70 of the planes last June after what it said was a "fleet requirement" review.
Unlike the Dreamliner, which was grounded in early 2013 for three and a half months because of problems with its lithium-ion batteries, Airbus — at this point — has decided to forego lithium-ion technology on the A350 in favour of traditional, but heavier, batteries.
So far, Boeing has secured more orders for its 787, but the program had a head start on Airbus, which was focusing on its colossal A380.
Boeing has 1,071 orders for its 787, with 228 of the jets now in service around the world. Airbus has 778 orders for the A350 from 41 different airlines and jet leasing companies including, British Airways, China Airlines, Delta Air Lines, Lufthansa, Singapore Airlines and United Airlines. The plane that flew to Frankfurt Thursday is the first of 80 such jets quickly-growing Qatar has ordered.
A larger version of the jet, which is scheduled to start flying in 2017, aims to compete with Boeing's long-range 777-300.
