Boeing and Emirates Airline are celebrating the delivery of the airline’s 100^th 777-300ER (Extended Range), marking another milestone in a partnership that began over two decades ago when the Dubai-based airline ordered its first 777.

With this delivery, Emirates will have 142 777s in operation and is the only airline in the world to operate all the 777 variants. With a current direct backlog of 51 777-300ERs, the 777 also comprises the largest part of Emirates’ 213-strong fleet.

“The Boeing 777-300ER is one of the most remarkable aircraft ever built, and its combination of efficiency, range and payload is second to none. Our customers are equally excited by the aircraft and its on-board product, and to date over 108 million passengers have flown on an Emirates Boeing 777-300ER,” said Sir Tim Clark, president of Emirates Airline.

“We have 204 more Boeing 777s on order, which supports over 400,000 jobs in the United States of America, including those from various suppliers such as General Electric which provides the GE90 engines that power all of our 777-300ERs,” said Clark.

Today’s 777-300ER is the most fuel and cost-efficient airplane in its class departing on time 99.5 percent of the time making it the most reliable twin-aisle aircraft in the world. It also has the highest cargo capability of any passenger airplane. Its 330-minutes ETOPS approval allows for more direct flights and decreases cancellations due to conditions at alternate airports.

The 777-300ER has consistently won many accolades including “Best Aircraft Type” which were awarded based on passenger preference polls, “Best in Class” based on fuel burn, passenger load cost and performance and “Best Residual Value for a Twin Aisle Airplane” among others.

“We are proud of our long-term relationship with Emirates and for the confidence they have in Boeing’s products and services beginning with the 777 and continuing with the 777X in the years to come,” said Boeing Commercial Airplanes president and CEO Ray Conner. “The operating economics and long-range capability of the 777-300ER have played a prominent role in the success of Emirates’ business strategy.”

At the 2013 Dubai Airshow, Emirates became one of the launch customers for the 777X by committing to 150 airplanes. The order was finalized in July of this year.

Each 777-300ER contains approximately three million components and assemblies, with more than 65 percent purchased through Boeing’s global supply chain.  More than 500 companies around the world contribute parts for the 777, with a significant percentage in the United States.

Boeing provides Emirates with essential support and services from its Boeing Edge portfolio of aviation services, including parts and components, Airplane Health Management to speed the detection and resolution of maintenance issues, Jeppesen Crew Rostering services to optimize flight crew scheduling, and AerData STREAM (Secure Technical Records for Electronic Asset Management) to manage aircraft and engine records.
