AirAsia has delayed the delivery schedule of ten Airbus A320 aircraft from its original schedule in 2012 to 2015.

The airline has delayed the delivery to switch its order to the new-generation A320 aircraft, which is more fuel efficient.

AirAsia previously agreed to order 175 Airbus A320 aircraft, but later delayed deliveries due to overcrowding in its budget terminal.

The airline said it would still take delivery of 14 aircraft in 2012 to allow the company to grow its joint ventures in the Philippines and Vietnam, according to Malaysia Sun.
