Aggregate value of shipments may be growing even more rapidly than tonnage, as certain high-technology sectors increasingly significant to the region's economy produce goods that are high in value relative to their weight. However, it does imply a consistently growing demand for facility and service capacity. In 1998, nearly 380,000 metric tons of air cargo were handled at the airport. This amount is 38 percent above 1990's level. Shipments did decline 3.4 percent from their 1997 total, affected by the Northwest Airlines strike in September.
Data cover freight, small packages, and mail.
Mail accounts for about one third of the total.
