So, the missus has exactly 15K American Airlines miles, with it being quite unlikely that she'll earn more, or at least enough for an attractive reward of some kind. (she has grown accustomed to flying in J with my miles!) There's currently yet another AA promo for sharing and buying miles so I could move those into my account for $150. Now conventional wisdom says that this would be quite stupid - no extra miles are generated - and so I should try to spend them out of her account. However, I've never seen an AA domestic flight (or US-Canada) that had both award space and wasn't already quite cheap. And there's that stupid late-booking fee for AA non-elite rewards (AA often opens space within that window). Therefore I always just pay for my AA flights and earn Tier Points and double Avios, etc. Can't think of any other useful use of 15K AA miles. Any other ideas for spending 15K AA miles? Or should I just grab them and then be happy on my next Etihad First Class flight?
