Chek Lap Kok handled record air-cargo throughput last month, according to the Airport Authority. Volume hit the 218,000-tonne level. By comparison, the second-highest month on record was November 2000, when cargo throughput reached 215,000 tonnes. The authority attributed the record volumes to continued strong consumer demand in the United States for mainland-made products. Labour unrest on US west coast ports had meant some shippers moved their goods by air.
