America West FlightFund (Pre-2005 US Airways merger) - HP/US Elite qualifying miles on BA flights?

Back well before the USAir merger was finalized (about 3 months ago), I booked a BA round trip (PHX/LHR) for the the last two weeks of December (WT+ upgraded to Business Class with BA miles) specifying that the mileage credit for the flight should go to HP . . . and this may be the difference between Gold and Plat.

Does anyone know whether HP/US will give credit for that trip?

According to this post (http://www.flyertalk.com/forum/showpost.php?p=4534850&postcount=19), you should be ok.

Thanks. I tracked it down and found this BA Partnership Ending announcement (http://www.americawest.com/awa/content/frequentflyer/mileagepartners/ba_announce.aspx) on the HP web site.
