BA is a non-US based carrier and oneworld are the only flights that pull up, so that is not the issue. What I am saying is that every single BA itinerary that I am able to price without YQ charges, with a US departure, will return a "flight not available" message at the very end of the booking process. However I was able to sucessfully put an AA itinerary on hold, though it is not quite what I want. No luck whatsoever with BA, and the other Oneworld carriers do not seem to drop YQ.
