TransAsia Airways of Taiwan has placed a firm order with Airbus for another six A321neo aircraft. The new aircraft will be part of the airline’s fleet expansion and will allow it to develop new routes to regional destinations. The aircraft will be powered by Pratt and Whitney PW1100G engines. The latest contract takes TransAsia Airways’ total orders for Airbus single aisle aircraft to 29, of which 11 have already been delivered. The carrier’s single aisle backlog now comprises 12 A321neo and six Sharklet-equipped A321ceo. In addition, the airline also has two widebody A330-300s on order, with first delivery scheduled later this year.
