Have a change in my award flights booked via Korean Air
Was booked on a non-stop ATL-HNL
Changed to a ATL-LAX-HNL (same departure time, arrival one hour later)

The original nonstop flight is still there on the same day, just shifted by two hours. What are the chances I can move back to the original flight, even though it shows no award availability? Extra stop in LAX is a huge inconvenience with kids on the trip.
