Boeing and China Airlines yesterday celebrated the delivery of the world's first co-branded 777 during a ceremony in Everett, marking the carrier's 10th 777-300ER.

In 2004, China Airlines became the first airline in the world to use Boeing's co-branded livery on its latest 747-400. That airplane was nicknamed the 'Blue Whale' by the airline and was the first co-branded twin-aisle airplane in the world.

With this delivery, China Airlines now operates a fleet of 10 777-300ERs and continues to bolster its long-haul routes to the North American and European markets.

Each of the airline's 10 777-300ERs are configured to seat 358 passengers in a three-class layout highlighted by the new 'Family Couch' seats in economy class.

China Airlines is the only airline in North Asia to feature the Family Couch seats, where three economy seats convert into a flat surface to provide passengers with added rest and relaxation.

The Boeing 777 is the world's most successful twin-engine, long-haul airplane. It is equipped with the world's most powerful GE90-115B commercial jet engine, and can travel, with a standard three class configuration, a maximum range of 7,825 nautical miles (14,490 kilometers).

Headquartered in Taoyuan, China Airlines is the largest carrier in Taiwan with a Group fleet of nearly 90 airplanes. The airline currently serves more than 13 million passengers annually to over 118 destinations across the globe.
