Oct 03, 2018: United Airlines have announced that it is expanding its Boeing 787 Dreamliner fleet again with a new order for nine 787-9 airplanes, the longest-range member of the super-efficient Dreamliner family. The deal is valued at $2.53 billion, according to list prices.

United Airlines says the order reflects its fleet strategy of replacing older widebody jets with new, advanced airplanes such as the 787-9, which can fly farther and use 20 percent less fuel with 20 percent fewer emissions. The US carrier, which announced a purchase of four 787-9s in July, has now ordered a total of 64 Dreamliners.

The latest deal continues the strong momentum for the 787 Dreamliner family, with net orders now above 100 for the year and just one shy of 1,400 since the start of the program. Nearly half of all 787 customers have returned to place additional orders for the airplane, helping to make it the fastest-selling widebody jet in history.

"The 787 Dreamliner has been so successful in the marketplace because of great partners like United Airlines that have taken the airplane's unrivalled performance to open new routes and offer passengers a wonderful travel experience," said Ihssane Mounir, senior vice president of commercial sales & marketing for The Boeing Company. "It makes all of us very proud to have United place a repeat order since its team has spent a lot of time with the Dreamliner and knows what it can do."

United began flying the Dreamliner in 2012, using the long range and fuel efficiency of the 787-8 and 787-9 to serve intercontinental routes such as Houston to Sydney and San Francisco to Singapore. The 787-9 can fly up to 7,635 nautical miles (14,140 kilometres) and serve 290 passengers in a standard configuration.

Later this year, the carrier is set to take delivery of the largest member of the Dreamliner family, the 787-10, which can seat up to 330 passengers in a standard configuration. While the airplane is capable of flying long distances with a range of 6,430 nautical miles, United has announced plans to debut its first 787-10 on premium transcontinental routes in the US, boosting its coast-to-coast schedules to offer passengers travelling between New York/Newark and Los Angeles and San Francisco more flights and more premium seats.
