Similar situation to others but can't find an exact answer. Have an AA booking on BA metal BOS-LHR-PSA in June. BA cancelled the LHR-PSA leg late last week but AA still shows that flight as confirmed and operating (and I'm sure the BOS-LHR schedule for June is about to get pruned from 4 flights/day in the next few days). I was in touch with AA Twitter and they said to wait until flight is cancelled on their end so refund application is not delayed. Question for the thread is how long after BA cancels should it show up in my PNR? This was cash paid for four P tickets and would love to get refund sooner rather than later...
