AirAsia has confirmed that it will defer taking delivery of eight of the 12 Airbus A320 aircraft scheduled for delivery in 2011.

The deliveries have been deferred over concerns whether a new lost-cost carrier terminal at Kuala Lumpur will be completed on time by the third quarter of 2011, AFP reports.

The Malaysian government had plans to build a new budget terminal to replace AirAsia’s existing facility.

The decision follows the carrier’s move in August to push back delivery of eight other A320 aircraft to 2014 from their initial delivery date in 2010, due to infrastructural constraints at Kuala Lumpur’s airport.

To date, AirAsia has deferred a third of the 48 aircraft deliveries that were scheduled for 2010 and 2011.

The Airbus A320 family of single-aisle jetliner can carry up to 187 passengers a distance of 3,700nm.
