alternatively you can use
KVS Availability Tool: Global Flight Availability, Award Availability, Fares, Timetables, Seat Maps
My screengrab does not include any award/upgrade booking classes. These can be retrieved, too, but availability of seats in those classes also depends on whether you want to use M&M miles vs. *A/Partner miles and your M&M Status.
