XIAMEN - Two Chinese mainland airlines announced Tuesday that they will fully refund passengers due to the cancellation of extra cross-Straits flights for the upcoming Spring Festival, which were obstructed by the Taiwan aviation authority.

Less than a month ahead of Spring Festival, the most important family gathering festival in China, the island's aviation authority has decided not to approve 176 additional cross-Straits flights operated by China Eastern Airlines and Xiamen Airlines.

Xiamen Airlines is based in Xiamen, Fujian Province, which faces Taiwan across the straits.

The airline announced that it will fully refund or help with ticket changes for the 10,000-plus passengers affected by the cancellation of the 70 extra cross-Straits flights.

The company also expressed its indignation toward the Taiwan authorities for taking "the approval of the flights as a bargaining counter" and ignore the travel needs of people on both sides.

Since direct flights across Taiwan Straits were opened in 2008, the airline has carried 4 million passengers on the route.

During the peak travel season, it is very difficult for passengers to book a ticket. This is not the first year Xiamen Airlines and China Eastern Airlines have added extra flights to cope with the travel demand.

Chen Kuangchung, a Taiwanese entrepreneur in Xiamen, said he was angry at the flight cancellation. He has taken the extra cross-Straits flights to return home for Spring Festival in previous years.

"Unable to buy an air ticket, I would have to travel by ship from Xiamen to Kinmen before taking a local airline to return to Taipei. The Taiwan aviation authority makes our trip home complicated," he said.

Shanghai-based China Eastern Airlines said among passengers affected by the flight cancellation are Taiwanese business people, tourists, and students.

The airlines said in its announcement that it had arranged the 106 extra flights to cope with the strong passenger demand despite its capacity restraint during the travel peak.

The number of the reserved tickets on the extra flights was 60 percent more than the amount at the same time of last year, to meet the traveling demand for 40,000 passengers.

The airline called on the Taiwan authorities to face up to the normal personnel exchange demands across the straits.

Regular direct flights across the Taiwan Straits have been available since July 2008, when Taiwan authorities lifted a partial ban on Chinese mainland tourists visiting Taiwan.

As the earliest Chinese mainland carrier to operate the direct flight service, China Eastern Airlines has operated 70,000 direct flights carrying 10 million passengers in the past decade.

However, the cross-Straits flight services do not meet the increasing market demand against the backdrop of growing economic, cultural, and personnel exchanges between the Chinese mainland and Taiwan.

China Eastern Airlines said that the Taiwan authorities should normalize the development of the cross-Straits civil aviation sector as soon as possible.
