In a report to senior CAAC officials, Chen Xiaoning, director of the research institute under the administration, said the potential impact of the terrorist attacks may be more serious than the countable losses.
In the four days after the attacks, when the United States shut its airspace to all air carriers, three Chinese airlines operating China-US flights lost 33.4 million yuan (US$4 million) in passenger business. In the cargo transportation business, they lost 40 million yuan (US$4.8 million).
