BEIJING ( TheStreet) -- This week could make or break 2014 financial results for China's domestic airlines, which are under enormous pressure as the country's economy cools and the yuan currency weakens.
Carriers are counting on heavy leisure travel to overseas destinations and Chinese tourist hot spots such as Hainan Island and Guilin during the May Day holiday period, which began Wednesday.
The country's biggest carrier China Southern Airlines (ZNH) said it added more than 5,000 seats to domestic routes for the holidays and bragged that flights were fully booked between its main hub Guangzhou and the cities of Auckland, Amsterdam, London and Vancouver.
Clouding the happy talk, though, were dismal first-quarter results released this week by top airlines, including China Southern.
The industry hit a bump on falling demand during the quarter, which included the Spring Festival holidays in late January and early February -- the busiest of three, big travel periods in China. Chinese also fly a lot for May Day and the national holidays in October.
Business travel across China fell significantly before and after Spring Festival from year-ago levels, according to a Haitong Securities industry report released Wednesday. Airlines responded to what the report called "a very serious supply-and-demand imbalance" by cutting fares.
As a result, China Southern posted a first-quarter loss of 306 million yuan ($48.8 million), compared with a profit of 57 million yuan in the same period last year. China Eastern Airlines (CEA) said it lost 205 million yuan, topping a 131 million yuan loss in the first quarter 2013. Hong Kong-listed Air China said it earned 92 million yuan in the January-March period, down 63% from last year's profit.
