AA has a transatlantic JV with BA where they share profits, so really, they couldn't care less if you take BA instead of AA. In fact, I suspect they would rather have XXX-PHL-YYY traffic be places like MEM, SYR, CVG and BUF for the XXX that DON'T get BA service as opposed to WAS or NYC that do. The idea is that PHL is the connecting hub for Atlantic traffic, and JFK and IAD are handling local O/D Atlantic traffic for the JV that goes to or connects at LHR. In that case you're really not out to optimize LGA/DCA-PHL-YYY compared to IAD/JFK-LHR-YYY.
