Boeing (BA) - Get Report said U.K.-based Monarch Airlines ordered six Boeing 787-8s with purchase rights for another four. The order is worth $916 million at list prices.

Chicago-based Boeing said the latest Dreamliner order gives it 377 firm orders, worth $59 billion at list prices, for the new plane. The Dreamliner has pushed Boeing ahead of rival Airbus as airlines order the plane for its fuel efficiency and lower operating costs.

With first delivery starting in 2010, Monarch will use the 787s as the basis of its future long-haul operations. Monarch's current long-haul fleet comprises Boeing 767s, A300s and A330-200s.

"Operating successfully in the leisure market requires flexible and innovative products. With the 787's longer-range capabilities, we will be opening up new destinations in the Americas, Asia and Africa," said Peter Brown, chief executive of Monarch Airlines. "We are very impressed by Boeing's use of innovative technologies on the 787, such as composite materials, which will reduce our maintenance costs."

Monarch Airlines, headquartered in Luton, is a provider of low-cost scheduled flights from bases at London Gatwick, London Luton, Manchester and Birmingham airports, as well as a major supplier to the tour-operating industry.
