These won't reveal flights for all the airlines' partners, but they will reveal a number of flights we may not have thought of.
Some other issues: most codeshares will not provide one with award seats (but some may). As well, some airlines (Qantas, for instance,) publish their award seats more than 330 days out, but some airlines, such as American Airlines, can only show / book them 330 days out, so it creates an issue for some.
