Cebu Pacific has signed a Memorandum of Understanding with European aviation giant Airbus for the purchase of 30 A321neo aircraft.

The carrier has also exercised existing options for seven more standard A320s, increasing to 41 its total firm orders for the Airbus single aisle product line.

“The A320 Family has played a key role in enabling us to build an efficient, profitable, value-based business,” said Lance Gokongwei, Cebu Pacific President and CEO. “The addition of more A320s and the A321neo allows us to expand further in the Asia Pacific region, and continue offering our trademark low fares.”

Cebu Pacific’s extensive network currently covers 33 domestic and 16 international destinations, including Osaka, Seoul (Incheon), Beijing, Jakarta, Bangkok and Singapore.

The A321neo is the largest model in the recently launched A320neo series, which incorporates new engines and large wing tip devices called sharklets. The advances will deliver fuel savings of 15% and additional range capability of over 500 nautical miles (950 kilometers), or the ability to carry two tonnes more payload at a given range.

For the environment, the fuel savings translate into some 3,600 tonnes less CO2 per aircraft per year. In addition, the aircraft will provide a double-digit reduction in NOx emissions and reduced engine noise.

The new engines types offered on the A320neo Family are CFM International’s LEAP-X and Pratt & Whitney’s PurePower PW1100G.
