KVS has a pretty decent interface that will show NW/CO/DL/KL/AF on a single search page. OK can be searched as well, though that is a different screen (and should also be available via seatcounter, I believe).

I'm not sure about the AM searches, but KVS doesn't seem to show it in any of their availability options.

As for the "private" inventory, that is generally reserved for elites. If you are not logged in on co.com the other carriers should see it.
