China Southern Airlines Co Ltd (1055.HK)(600029.SS) estimated 2010 profit would be about 15 times that of 2009 as demand for passenger and cargo transportation services soared.

In a filing with the Hong Kong bourse late on Tuesday, the Chinese airline said net profit attributable to equity holders amounted to 358 million yuan ($54 million) in 2009 in accordance with Chinese accounting standards.

China Southern Airlines said it also would report currency gains reflecting the appreciation of the yuan against the U.S. dollar. (US$1=HK$7.77)
