AA and OW offer $1.1 billion

Bloomberg reports that AA, together with Oneworld and TPG, will offer as much as $1.1 billion investment to Japan Airlines. This is double of the amount Delta offered. The report doesn't provide investment distribution though. It would be interesting to see which OW carriers and how much they are willing to invest on JAL. My bet will be AA is the one who provide most of the investment since they will be the biggest loser if JAL to jump ship to Delta. But this is just MY GUESS
