Austrian Airlines kicks off the celebration year with super attractive roundtrip fares from Beijing and Shanghai to Europe starting at RMB4,500 (excluding taxes and surcharges). The earlier the tickets are booked and purchased,the lower the airfares are for travel during the period from February 13 to April 15,2005.……展开更多

With nearly 7 million passengers flown in the first ninemonths, an increase of load factor by +1.7% was achieved. Based on this traffic performanceand a very satisfactory advance booking situation for the remaining three months,展开更多
