I do not think LH will discharge AI, they will try instead to get 9W on board as an addition. If it happens it will be interesting--since 9W just lost their previous ex-LH hand CEO to BMI and usually this was a deciding factor towards Star, and because getting an airline with a higher service class will have obvious implications to current LH operations in India.
However since it seems BA is IT sponsor, I would prefer AA step up and sponsor Jet to OW, it should not be that difficult. And it seems that at the moment ST is relatively in shambles, after the JAL debacle.
