Taipei-based China Airlines (CAL) announced Tuesday that from September for a limited period, it will cut prices by at least 10 percent for individual passengers flying economy class on routes between Taiwan and certain cities in China. From Sept. 1-Dec. 31, passengers on CAL flights from Taiwan Taoyuan International Airport and Taipei's Songshan Airport to China's Beijing, Shanghai's Pudong and Hongqiao airports, Nanjing and Ningbo, as well as flights between Kaohsiung and Pudong Airport, will enjoy the cheaper prices, the company said. Under the program, the prices of one-year, three-month, one-month and 14-day validity economy round-trip tickets on the routes will be cut, according to the company. CAL said the biggest cut will be on one-year tickets for flights between Taipei and Nanjing and between Taipei and Ningbo, at 27.3 percent. Group tickets will not be entitled to the price cut. CAL Vice President Brian Chou, who is in charge of marketing affairs, said the cuts are being initiated to celebrate the Aug. 31 first anniversary of the launch of regular direct flights between the two sides of the Taiwan Strait. Each week, 28 round-trip flights will be subject to the discounted fares, Chou said. Asked about the expected impact of the cuts on the company's revenues in the fourth quarter, given the fact that 20 percent of the total CAL revenues are generated from cross-strait services, Chou declined to make a detailed assessment, saying only that 'they will decline.' Following CAL's announcement, EVA Airways, Taiwan's second-largest carrier, announced that it would follow suit on its cross-strait flights, as well as on flights to elsewhere in Asia, Europe and America. Prices for individual economy class flights from Taoyuan and Kaohsiung to Beijing, Shanghai, Ningbo and Nanjing will be cut by 10 percent to 15 percent, while a price drop of between 5 percent and 15 percent will be implemented on its global routes, according to the company. Taipei-based TransAsia Airways, which also operates cross-strait services, said it would not decide whether or not to follow the price cuts until the following day.
