Typhoon Utor and the ongoing industrial action by Cathay Pacific pilots have been blamed for a decline in passenger numbers at Chek Lap Kok airport last month. The Airport Authority said passenger volume in July was 2.91 million, down 4.4 per cent on the same month last year. Cargo remained weak, with total shipments down by 14.2 per cent year-on-year to 162,000 tonnes. 'The combined effects of Typhoon Utor and Cathay pilots' industrial action saw passenger numbers drop slightly at the airport,' an authority spokesman said. But he said total passengers in the 12 months to July stood at 33.8 million, a five per cent rise on the same period the year before. Total flights also increased by 8.2 per cent from 15,495 to 16,760, from June to July. 'Aircraft movements increased despite a number of flight cancellations caused by Utor and the pilots' industrial action,' the spokesman said.
