From the few articles I have read, technically they do not pass with your passing, they vanish. However, in some (many? most?) cases I have heard of airlines putting them in the spouses account. I have not heard of them going any other place than spouse. I have yet to hear of a case where they were specifically willed to an individual and then were provided to that individual by the airline. I have heard nothing at all about hotel points. I think this is an interesting issue and look forward to what information others can pass on. As I am single (though young) and have huge reserves of points and miles it would be great that if I died suddenly I could leave them to someone.
