Air travel chaos across Europe caused by the volcanic eruption in Iceland continued Sunday, impacting tourists and business people's schedules and causing economic loss to Chinese airlines and tourism agencies.

Air China canceled five one-way flights and eight return flights to European cities including Paris, Frankfurt and Moscow Sunday, according to a notice on its website. "The cancellation was due to closure of most European airports, and we will keep a close eye on the latest situation, "said Zhu Mei, an Air China spokeswoman.

Other carders including China Southern Airlines, China Eastern Airlines and Hainan Airlines have also canceled most flights to Europe, according to the Civil Aviation Administration of China.

"This is the first time we met such a natural disaster, and we can only wait and keep in contact with our tourists," said Hun Ping, an employee on duty at China International Travel Service's(CITS) branch in Beijing Sunday.
