Hong Kong's Dragonair is about to announce the expansion of its fleet with the purchase of two new Airbus A320 aircraft and the lease of another higher-capacity A330. Analysts said the move was a strong vote of confidence in the airline's future growth prospects. H.G. Asia Securities airline analyst Declan Magee said the purchase of the aircraft suggested that after a period of difficulty in expanding its services in China, the management felt confident about developing the business. A source close to the deal said details of the purchase, which were leaked to specialist magazine Flight International , were 'broadly right'. It reported that Dragonair placed orders for two A320s for delivery in 1998 and 1999. The airline has seven leased A320s and three leased longer-range, mid-capacity A330s. It also plans to lease an A330-300 from International Lease Finance, to enter service next year. The deal also is said to include the option to buy another five A320s. This order follows the launch and expansion of several services in China and Taiwan.
