American Airlines' partners in oneworld, the industry alliance that includes British Airways, are devising incentives to help keep Japan Airlines Corp. in the group.

Each carrier is crafting its own offer, which will then be sent to JAL and the Japanese government as one proposal, oneworld managing partner John McCulloch said in an interview. JAL has applied for a government bailout.

"There is a concerted, coordinated effort by the oneworld carriers to put together a package of incentives," McCulloch said. "The package is very much an effort to persuade them to stay."

The sweeteners would bolster efforts by American to ensure JAL stays in oneworld as Delta Air Lines tries to lure the money-losing carrier to the SkyTeam alliance. American said last week that private-equity firm TPG Inc. was prepared to team up on a possible investment in JAL.
