As confirmed by the international US carrier, American Airlines and TPG, the private equity firm, on Thursday jointly offered to inject funds worth as much as $1.1 Billion into the struggling Japan Airlines.

At a press conference in Tokyo, the American airlines operator shared that its total investment in the Japanese carrier, however, would be over $1.8 Billion, taking into account the financial assistance and the subsequent revenues that the funds injected would generate.

"The total incremental financial support from American, one-world and TPG is in excess of 1.8 billion dollars and far exceeds any other available proposition", American Airlines said.

Japan Airlines, which is currently Asia's biggest carrier, has been on the brink of declaring bankruptcy as result of its mounting debts, huge pension cuts, mismanagement and bearing the brunt of the global financial crisis which hit the complete aviation industry.

Both American Airlines and arch rival Delta Airlines have been pegging to buy a substantial stake in JAL, as it would mean a foothold in one of Asia's biggest and strongest economies.

"If there was interest by the government in raising more money than that (the one billion dollar package) by introducing outside, third-party investors, we would be happy to support that effort as well", Delta President Edward Bastian has been quoted as saying.
