Air France KLM said it passenger and cargo business had shown a "marked" recovery in terms of traffic and unit revenues in May due to an improvement in the economic environment and prudent capacity management.

Cargo traffic rose 8.7 percent with the load factor up 7.8 points at 70.6 percent of capacity.

The airline made no mention of the impact of the volcanic ash cloud that forced European airport closures in early May, but the closures were less severe than in April. (Reuters)
