A few things. Weather happens, get over it. Everybody gets inconvenienced by it-missed meetings, job interviews, wedding, funerals. Second, unless you are a top tier flyer AA is not going to put you on another carrier. And neither would other carriers. Third, you had the choice of being rebooked on a later flight or cancelling for a full refund and doing whatever. Buying a ticket on another carrier, cancelling the trip. Since you didn't pay to fly on AA why would you expect to get mileage credit, particularly towards elite status? If I go the airport and look at the AA planes take off should I get some kind of mileage credit?
