I've got my full complement of $200 left, and unfortunately no plans to fly AA in the near future. I also have BA Silver status, so a lot of the lounge/seating benefits are already available to me.
I am looking at spending on a Mileage Multiplier. I understand this is only available with a booking. If I were to make a reward booking, pay for the Mileage multiplier and then cancel the award booking, I am assuming that would achieve my goal of using the $200 credit almost fully?
