I booked an award for my parents this coming May from LAX to FRA, with a change of planes in IAD, all on United metal. They originally had just under 90 minutes to connect, but they received a call today that they were rebooked on a flight that now leaves them with 50 minutes to connect. What makes no sense at all is that the original flight 31 is still there, it just leaves around 30 minutes earlier than originally scheduled (granted, there may have been an equipment change, but I'm not sure). .bomb shows that there are still award seats on flight 31, but the call center says they can't see it and of course I can't reroute through another city unless I pay $150. Since they are in economy and my mom doesn't walk that well, I'm afraid that 50 minutes won't give them enough time to connect. Do I have any options at this point, aside from hoping that the call center eventually sees seats on flight 31? As a side note, why were they automatically placed in Economy Plus seats on the new flight and a request to pay $59 per passenger appears when I view the new seats?
