Sorry if this has been asked, but I cant find it anywhere. I understand that once US Air and American merge, they will continue to operate under 2 seperate compaines. But what will happen to miles? I a masking as I do not fly US Air, but I am considering applying for their credit card to get the bonus miles, if the miles will then be merged into my American account after the transfer. But I am not sure what is going to happen to US Air miles and American miles if they are going to continue to operate as 2. Thanks everyone.
