Flagship carrier Garuda Indonesia has signed a contract with European plane maker Airbus for 25 A320 jets including 10 A320neos after agreeing a deal in June, Airbus said Tuesday. At list prices the order is worth an estimated $2.18 billion (1.53 million euros). The jets will replace the Boeing 737 aircraft flown by Garuda\'s low-cost unit, Citilink. The A320neo is claimed to be 15-percent more fuel efficient than the classic model, with new high-tech engines making the difference. The two companies announced on June 21 that they had signed a memorandum of understanding on the sale.
