MIAMI — The long haul affiliate of Asia’s largest low cost airline–AirAsia X has placed a firm order for 55 Airbus A330neo aircraft. This order makes it the third firm order since the A330neo program was lunched at the Farnborough Air Show earlier this year.

Currently, Delta, CIT Group, and AirAsia X have a combined total order of 95 A330-900neo aircraft on order.

“This order from AirAsia X is a major endorsement of the A330neo as the most cost-efficient aircraft in its size category,” said John Leahy, Chief Operating Officer, Customers, Airbus. “With the A330neo in its fleet, AirAsia X will benefit from even lower operating costs as it expands it network and reach, enabling more people to fly further more often than ever before. We look forward to AirAsia X becoming one of the first operators of the latest version of the highly successful A330.”

“This latest deal with Airbus will enable AirAsia X to consolidate its growth rate in 2015-2017 before ramping up deliveries from 2018 onwards.” said Tan Sri Tony Fernandes, Co-Founder and Director of AirAsia X. “The A330 has proven itself to be exactly the right aircraft for our business model, combining low operating costs, long range flying capability and high levels of comfort. We are extremely excited about the even greater levels of efficiency that will come with the A330neo, which will play a key role in enabling AirAsia X to maintain its position as the long haul low cost leader.”

Also in a press release, Airbus writes that the A330neo is built “on the proven economics, versatility, and reliability of the A330ceo.” However, the A330neo will boast the latest Rolls-Royce Trent 7000 engines, new cabin features, and aerodynamic enhancements which will all contribute to an expected reduction in fuel of 14% per seat, making this aircraft the most cost-efficient in its size category.

Deliveries of the A330neo are expected to begin in 2018.
