Has anyone successfully used their own United MP account number for service under someone else's name? So for instance, if my parents wanted to get DirecTV and did not have a United account, would they be able to sign up for service and enter my MP account number and I receive the miles? I have no idea if DirecTV shares customer information with United or if they just say that the requirements for earning the miles has been met and then United deposits the miles into the account number that DirecTV gives them. I recently just signed up for DirecTV service myself and all I was asked was to supply a United MP account number and once I hit submit, it said that the miles should arrive within 6-8 weeks. Thanks in advance for anyone who can shed some light on this for me.
