as the ACJ350 corporate jet by Airbus Corporate Jets (ACJ), offering a range for 25 passengers for the -900 derivative. A350-900 The A350-900 is the first A350 model; it has a MTOW of , typically seats 325 passengers, and has a range of . Airbus says that per seat, the Boeing 777-200ER should have a 16% heavier manufacturer's empty weight, a 30% higher block fuel consumption, and 25% higher cash operating costs than the A350-900. The −900 is designed to compete with the Boeing 777 and 787 (777-200ER/LR, and Boeing 787-10), while replacing the Airbus A340-300 and A340-500. A proposed A350−900R extended-range variant was to feature the higher engine thrust, strengthened structure, and landing gear of the MTOW -1000 to give a further range. Philippine Airlines (PAL) will replace its A340-300 with an A350-900HGW ("high-gross weight") variant available from 2017. It will enable non-stop Manila-New York City flights without payload limitations in either direction, a flight. The PAL version will have a MTOW, and from 2020, the -900 will be proposed with the ULR's MTOW, up from the for the original weight variant and the certified variants, with the large fuel capacity. This will enable an range with 325 seats in a three-class layout. In early November 2017, Emirates committed to purchase 40 Boeing 787-10 aircraft before Airbus presented an updated A350-900 layout with the rear pressure bulkhead pushed back by . After Emirates' Tim Clark was shown a ten-abreast economy cabin and galley changes, he said the -900 is "more marketable" as a result. The average lease rates of the first A350-900s produced in 2014 were $1.1 million per month, not including maintenance reserves amounting to $18 million after 10–12 years, and falling to $940,000 per month in 2018 while a new A350-900 is leased for $1.2 million per month and its interior can cost $12 million, 10% of the aircraft. By 2018, a 2014 build was valued $108M falling to $74.5M by 2022 while a new build was valued for $148M, a 6+12year check cost $3M and an engine overhaul $4–6.5M. A350-900ULR The MTOW of the ultra-long range -900ULR has been increased to and its fuel capacity increased from within existing fuel tanks, enabling up to 19-hour flights with a range, the longest range of any airliner in service . The MTOW is increased by from the previously certified variant. Because of the A350-900's fuel consumption of per
