As far as Diners Club is concerned, point transfers to someone else's account are allowed, except for AA, BA, Air France, and Frontier. This has been the case for many, many years. And, no, it does not have to be the same last name. Make your request by telephone, and do not forget to take down the confirmation number for the transfer.
