Malaysian budget carrier AirAsia has placed a firm order for 50 Airbus A320 family aircraft, and placed options on a further 50 aircraft.

Deliveries of the aircraft will take place from 2008 and run through to 2013.

AirAsia has yet to confirm an engine selection but the airline has previously selected CFM International CFM56 powerplants for its A320s.

During last July’s Farnborough Air Show, AirAsia firmed up 40 A320 options and took an additional 30 options on the type – adding to a previous firm order for 60.

AirAsia operates a mix of A320 and Boeing 737 aircraft.
