DL/VS - DL has a significant investment stake in VS where there is probably a financial reason to make it happen as frequent flyer currencies will matter to them.
AA/BA - AA doesn't have an interest in Avios nor does BA in AAdvantage miles. Fare paying results is all that matters due to the joint venture agreements in place across the Atlantic.
