Has anyone had the booking carrier tell them that they were out of luck when a schedule change broke a connection? I have an upcoming *A award ticket in C on AC & NZ. AC monkeyed with its schedule and broke my return connection in NRT. US (the booking carrier) is telling me to go pound sand because there is no other award availability for that itinerary on nearby dates. Is my ticket truly worthless now? Or are there some magic words that might help the agent figure out a way to rebook me?
