or its range by , but this led to a fuel burn penalty of "a couple of percent", according to John Leahy. The previously planned optimisation to the structure and landing gear was not beneficial enough against better commonality and maximum takeoff weight increase by 11t from 248t. The −800's fuselage is 10 frames shorter (six forward and four aft of wing) than the −900 aircraft. It was designed to supplement the Airbus A330-200 long-range twin. Airbus planned to decrease structural weight in the -800 as development continued, which should have been around airframe 20. While its backlog reached 182 in mid-2008, it diminished since 2010 as customers switched to the larger -900. After launching the Airbus A330neo at the 2014 Farnborough Airshow, Airbus dropped the A350-800, with its CEO Fabrice Brégier saying "I believe all of our customers will either convert to the A350-900 or the A330neo". He later confirmed at a September 2014 press conference that development of the A350-800 had been "cancelled." There were 16 orders left for the -800 since Yemenia switched to the -900 and Hawaiian Airlines moved to the A330neo in December 2014: eight for Aeroflot and eight for Asiana Airlines, both also having orders for the -900. In January 2017, Aeroflot and Airbus announced the cancellation of its -800 order, leaving Asiana Airlines as the only customer for the variant. After the negotiation between Airbus and Asiana Airlines, Asiana converted orders of eight A350-800s and one A350-1000 to nine A350-900s. Longer A350-1000 In 2011, Airbus redesigned the A350-1000 with higher weights and a more powerful engine variant to provide more range for trans-Pacific operations. This boosted its appeal to Cathay Pacific and Singapore Airlines, who were committed to purchase 20 Boeing 777-9s, and to United Airlines, which was considering Boeing 777-300ERs to replace its 747-400s. Emirates was disappointed with the changes and cancelled its order for 50 A350-900s and 20 A350-1000s, instead of changing the whole order to the larger variant. Assembly of the first fuselage major components started in September 2015. In February 2016, final assembly started at the A350 Final Assembly Line in Toulouse. Three flight test aircraft were planned, with entry into service scheduled for mid-2017. The first aircraft completed its body join on 15 April 2016. Its maiden flight took place on 24 November 2016. The A350-1000 flight test programme planned for 1,600 flight hours; 600 hours on the
