Can you explain this a little more? I didn't think there was a single instance in which it was advantageous to use the Mileage Multiplier.
Also, the fact that he's being given the option of the Mileage Multiplier means that he is purchasing a non-reward ticket. The Mileage Multiplier is not an option, as least as far as I know, when booking award flights.
