Whether you want to believe it or not, my understanding is correct, in order to buy a WT+ ticket it
must be booked at BA.com and can't be upgraded with AA SWU's or miles. I've been looking this as I'm trying to do the same using my AA miles for WT+ LAX-DAR but can't do it.
By the way, I'm trying to help you so the snippy response wasn't warrented

AA reservations is capable of booking a WT+ fare in the W bucket. Yes, it would be on BA ticket stock but AA phone reps are able to provide this service.
Secondly, the link I provided clearly states AA miles can be used to upgrade on BA and IB flights. Why are you debating this simple point?
I'm sorry you have had difficulty booking your itinerary but only weeks ago I helped a friend upfare an AA codeshare ticket to a WT+ fare booked in W, and then use AA miles to upgrade into CW.
Effective October 1, 2010 AAdvantage members may use AAdvantage miles to upgrade on American Airlines, British Airways and Iberia flights. Miles may be used to upgrade yourself or anyone you designate* at the time of ticketing.
Codeshare flights marketed by American Airlines, British Airways and Iberia and operated by any of the three carriers are also eligible to upgrade. In order to upgrade on a flight operated by British Airways or Iberia, your original ticket must be booked directly with American Airlines (via Reservations or AA.com).
