Cargo tonnage on freighters at Amsterdam Airport Schiphol fell for the second straight month in October, reversing a long-term expansion of all-cargo business at the key European gateway.

Schiphol officials said the freighter tonnage fell 4.1 percent in what is traditionally one of the year's busiest periods for international air cargo traffic.

Amsterdam's overall cargo business was off 0.7 percent in October as cargo carried on combination airlines grew 4.1 percent.

Freighters provide 56 percent of the cargo tonnage at Amsterdam Schiphol, one of Europe's top four airports for freight.
