March 29, 2018, © Leeham News: Boeing’s 787-9 has opened new ultra-long routes such as Qantas' first flight from Perth in Australia to London Heathrow last weekend (a 7,900nm, 17-hours flight). The 787-9 has been the undisputed long-haul star under 300 seats, with Airbus A350-900ULR underbidding the Boeing 777-200LR’s fuel burn for over 300 seats ultra-long haul flying.
But the competition for below 300 seat ULR alternatives will change in two years. Airbus A330-800 is then available in its 251t version. It will fly longer than the 787-9, according to Airbus.
The range of 7,635nm given by Boeing for the 787-9 and 8,150nm by Airbus for the A330-800 is not using the same seating and fuel reserve rules. We use our performance model to weed out the differences, to make an apples-to-apples comparison of the 787-9 and A330-800 as ULR aircraft.
