I think that this article is pretty clear:
"The US Airways partnership allows AAdvantage members to pool miles with Dividend Miles when redeeming select awards."
Thus not all awards are available for the pooled miles.
I do find it odd that Randy (who is great!) starts his latest AirMail by saying that the magazine made a "terrible" error by putting the wrong page number on the cover of their last month's issue. While this issue again has many inaccuracies. Randy - you really should have somebody proof your magazine carefully before it goes out. And correct or refute ltters to the editors that may be inaccurate or misleading.
Of of the many errors in this issue is an EyeSpy telling you to go to aolaadvantage.com to sign up for a Citibank checking account. Elsewhere in the same issue you say that the site is not up yet. As article on USAirways double miles promotions says that TWA is is only carrier to match "United's" promotion, etc. And yes, I do read your magazine cover to cover. Do keep up the good work, but maybe hire a proofreader?
