Hong Kong International Airport's (HKIA) passenger traffic rose by 5.9% to 4.6 million in October this year compared with the same period last year.
The total aircraft movement at the airport increased by 5% to 28,500 flights, but its cargo volumes dropped by 8.2% to 342,000 tonnes.
Stanley Hui Hon-chung, chief executive of Airport Authority Hong Kong (AAHK), said: "[The] growth in passengers and aircraft movements was stable, while declining trade in the US and European markets amid their economic situations - as well as Thailand, which has been adversely affected by recent flooding - negatively impacted cargo performance."
The growth in passenger traffic in October was mainly driven by visitor traffic, which registered a 7% increase over the same month last year, HKIA said.
The cargo decline in October was mainly attributed to the 8% year-on-year drop in exports. Imports and transshipments decreased by 8% and 10% respectively compared to October 2010, HKIA said.
