Dubai's Emirates Airlines has become the world's largest airline operator of Boeing 777 aircraft with the arrival of its 78th Boeing 777 on Thursday, Qatar News Agency "QNA" reported today. Emirates has another 28 Boeing 777s pending delivery, worth over $7 billion at list prices, and it is also the only airline to operate every model in the Boeing 777 family: -200s, -200ERs, -200LRs, -300s, -300ERs and freighters, the business portal "Trade Arabia" reported. The newest addition to the Emirates fleet is a Boeing 777-300ER configured for long distance journeys. "The 777s form the backbone of our fleet, and we have configured these aircraft to give us maximum flexibility in terms of route deployment," President of Emirates Airline Tim Clark said. "Emirates 777s today fly to six continents from our Dubai hub, operating routes within a two-hour distance to long-range journeys of 16 hours non-stop," he added.
