We have non refundable, international round trip tickets traveling to and from London in June which we will probably end up cancelling. Our outbound flight is one connection on AA and I and am pretty sure that AA will fly those flights as planned, since they are flying them right now. The return was a direct flight to our home city on British Airways (all booked on one ticket through American). I am almost 100% certain the return direct flight will be cancelled by BA and American will reroute us on a connecting itinerary. It looks like they could do so without moving our arrival or departure time by more than 4 hours which would prevent us from qualifying for a cash refund because of a schedule change. My question is, will a reroute from a direct flight to a connecting flight on the return leg enable us to cancel the whole itinerary for a cash refund?
