Dubai-based Emirates Airline has announced that it has placed an order for 50 new Boeing 777-300ERs (extended range) planes, as well as options for an additional 20 units of the popular twin-aisle commercial jetliner.

The 777-300ER airplane carries 365 passengers up to 7,930 nautical miles (14,685 km). Boeing incorporated several performance enhancements for the 777-300ER, extending its
"This is an extremely proud moment for us as it not only underscores Emirates' ongoing confidence in the 777, but also makes this the single largest order by dollar value in Boeing's history," said Boeing Commercial Airplanes president and chief executive officer Jim Albaugh.
"As the largest operator of the 777 in the world, Emirates has played an important role in development of the airplane and its input over the years has been invaluable in the development of the 777 programme," he added.
