PARIS/FRANKFURT, July 9 (Reuters) - Figures from Lufthansa (LHAG.DE), one of the world's biggest carriers of air freight, a key barometer of world trade, showed the airline slump continuing, while Air France-KLM braced for temporary lay-offs.

Continental Europe's largest airlines -- Lufthansa by market value and Air France-KLM (AIRF.PA) by revenues -- were unable to point to significant signs of recovery in separate announcements on Thursday, though Frankfurt airport operator Fraport (FRAG.DE) sounded a rare but still fragile note of optimism.

Germany's Lufthansa said shipments of cargo and mail fell 14.3 percent in June after 10 percent in May as a slump in economic activity continued to weigh. [nL8117517]

"In the air freight sector ... the market environment remained weak in June," the German flag carrier said.

Passenger traffic retreated 5.2 percent in June, it said, though this was better than the 7 percent some analysts had feared, and an improvement on May's fall of 7.1 percent.

Cargo flows are under the spotlight as economists look for clues on physical trade movements. They have been hit both by economic weakness and a crisis over trade financing that G20 countries have promised to address by pumping in cash.

Just under half of international trade by value is shipped by air, according to airline lobbyists, and Lufthansa is the world's second-largest cargo network after Korean Air (003490.KS). When Air France and KLM, which merged in 2004 but still operate separately, are combined, they outrank Lufthansa.

FRAPORT MORE OPTIMISTIC
