This seems like the relevant thread for this, but my search parameters didn't turn up any wiki or reference:
Like many others in this thread - I'm likely going to can my Chase United Club card before my renewal later this year and move to a card that's program agnostic. That said, I'm still likely going to be flying United given my travel patterns so what I'd like to do is credit PQM/PQD to United, but credit RDM to another *A program like NH or SQ. Is that even doable? If yes, what do I need to do?
