I realize this is a partner route. What's strange is on the F9 route map, it says DEN is the only nonstop destination (makes sense). But in either the flight search or flight schedule search, it won't accept DEN as a destination; it'll accept every airport but DEN. Is that because somehow the RIW-DEN route is not sold?

Also, I can't find any day this year when IND-RIW has award space (not even for 20K OW), even though there are paid seats available on most days. I know DEN-RIW uses a small aircraft, but is RIW that popular that all award space are snatched up? Or is it because F9 doesn't release award space on this particular route?
