One thing that there is no mention of either way in the US non-OW partners award chart or on the web site is, can US and/or AA flights (i.e., domestic connections) be used in conjunction with these non-OW airlines.
Does anyone know either way? (Through having made, or attempted to make, a booking.)
If it can be used together with US and AA flights for domestic connections, then it still has some potential. But if not and it's only one or more of those airlines, withOUT any US or AA flights allowed, then, however, it is severely limiting.
*When this is known, would be also a good idea to update the wiki to reflect that.
