Amsterdam Schiphol Airport has reported a 2 per cent rise in cargo traffic between January and September, compared with the same period of last year. The airport now expects cargo traffic to grow just 3 per cent this year, down from an earlier forecast of 6 per cent. 'Air cargo volume rose only by 2 per cent due to the fact that during the summer period there were not enough slots available to accommodate new cargo operations' full freighters,' a Schiphol spokesman said. In the third quarter, cargo volume fell 1.4 per cent year-on-year. The implementation of slot co-ordination, coupled with a maximum number of movements per year, was adversely affecting traffic growth, Schiphol officials said. Growth in aircraft movements, passengers and cargo transport was influenced by the airport's adoption this year of a fully co-ordinated system, officials said. About 25.8 million passengers passed through the airport terminal, up 10.2 per cent from last year. The number of air transport movements rose 9.3 per cent to 284,730. The airport has revised its 1988 forecast for passenger traffic growth to 10 per cent, down from 11 per cent. Airport officials said passenger traffic to and from North America was affected by the Northwest Airlines strike. The strike restricted passenger traffic growth in the third quarter to just 8.7 per cent. Separately, Schiphol will be one of six candidates allowed to bid for 35 airports that the Mexican Government is privatising.
