Dubai-based Emirates became the world’s largest operator of Boeing’s twin-jet 777 airliner with the delivery of its 78th 777 in ceremonies at Boeing’s Everett plant.

Emirates operates the full range of 777 models including the -200, -300, the -200LR (longer range) and the 777 Freighter.

The airline has an additional 28 777s on order valued at more than $7 billion at list prices, said Boeing.

Emirates accepted its first 777 in 1996. The airline’s business plan calls for making Dubai a worldwide hub for flights between Europe, Asia, Africa and North America.
