TOKYO —

Struggling Japan Airlines Corp has entered talks with Air France and KLM over a capital tie-up, a newspaper said Saturday. Asia’s biggest airline hopes to expand its businesses in Europe via the capital alliance with Air France and KLM, according to the Yomiuri newspaper, Japan’s top-selling daily. The report cited no sources and officials at the Japanese airline, known as JAL, could not be reached for comment Saturday.

JAL said Friday it was considering various tie-ups with a wide variety of potential partners but nothing had been decided.

JAL is in the midst of major restructuring as the airline incurred its biggest-ever quarterly net loss of 99 billion yen in the three months to June. It has forecast a net loss of 63 billion yen for the current fiscal year to March 2010, and plans to cut the number of flights and slash costs by 53 billion yen during the current fiscal year and another 100 billion yen in the next fiscal year.

Apart from Air France and KLM, JAL is also seeking a bigger capital injection from Delta Air Lines, the Yomiuri said.

Delta—the world’s biggest airline operator—is considering making a cash infusion of a couple hundred million dollars to aid JAL, according to a person briefed on the talks Friday.

In exchange for the infusion, the person said Delta could get a stake in JAL, an expanded presence in Japan and coveted access to the closest airport to the Tokyo business center. The Yomiuri said Delta could become a top shareholder of JAL.

But the talks between JAL and Delta were in their preliminary stage, and it was unclear what form a partnership between the two airlines might take, said the person, who asked not to be identified by name because of the sensitivity of the discussions.

Japan’s Nikkei business daily quoted a senior JAL official Saturday as saying the tie-up with Delta would be difficult due to the Japanese airline’s alliance with American Airlines.

JAL has a codeshare agreement with American Airlines as part of its participation in the oneworld alliance. Delta’s SkyTeam alliance currently doesn’t have a Japanese partner.

Instead of Delta, JAL may seek a capital injection from American Airlines, the Nikkei said.

Among U.S. carriers, Atlanta-based Delta has a relatively large Japan presence by virtue of its acquisition last year of Northwest, but its market share there is still dwarfed by that of Japanese carriers. In the Tokyo market, Delta operates from Narita Airport, the main international airport.

Delta has not been allowed to serve Haneda Airport, a mostly domestic airport that is much closer to the center of Tokyo. The U.S. and Japanese governments have been in talks about air service between the countries, though it is unclear how those talks will turn out. 

A passenger jet made an emergency landing at Germany's Stuttgart airport on Monday, but there were no significant injuries, airport authorities and a passenger said.

The Fokker 100 (Contact Air), which was on an internal flight from Berlin's Tegel airport, had problems with its landing gear, the airport said on its Web site.

It said five passengers suffered shock and a stewardess was taken to a hospital for observation.

Among those on board was Franz Muentefering, the chairman of one of Germany's governing parties, the center-left Social Democrats.

"It was a very serious situation," Muentefering said in a statement released by his party. "We circled for a long time, attempted the approach and then had to make an emergency landing."

"All remained uninjured," Muentefering said, thanking the plane's captain for a "masterly performance."

The airport's runway was closed temporarily.
