TRAFFIC AND CAPACITY STATISTICS — JUNE 2003

Passenger Traffic

Due to market circumstances, KLM reduced passenger capacity by 9 percent compared to last year. As passenger traffic was 9 percent lower year-on-year, load factor was more or less stable at 79.7 percent.

On the Asia/Pacific route area, the effects of the SARS epidemic were still apparent. Traffic decreased by 28 percent with capacity 23 percent lower than last year. Load factor was 5.8 percentage points lower year-on-year at 77.9 percent. Towards the end of the month, daily load factors exceeded last year’s levels, albeit on an average of 20 percent lower capacity.

On the North Atlantic, load factor increased by 0.7 percentage points to 89.2 percent. Traffic was 8 percent lower year-on-year, while capacity decreased by 9 percent.

Traffic on the Middle East routes has recovered from the Iraq-war. As KLM has been prudent in adding back capacity on the MESA route area, load factor increased by 3.9 percentage points to 77.7 percent.

In Europe, load factor increased by 1.9 percentage points to 79.6 percent. Traffic was virtually at the same level as last year, while capacity decreased by 2 percent.

Cargo Traffic

Cargo traffic was at the same level as last year on a 2 percent capacity increase. Cargo load factor decreased by 1.3 percentage point to 72.3 percent. Load factor on the Asia Pacific routes decreased by 0.9 percentage point to 84.5 percent. Traffic increased by 1 percent on a 3 percent capacity increase. Traffic on the North Atlantic routes increased by 5 percent while capacity increased by 7 percent. As a consequence, load factor decreased by 1.8 percentage point year-on-year to 72.6 percent.
