In the context of alaska + other airline awards, this could add a lot of value for a lot of kvs users. For the airlines that are displayed on alaska booking website anyway, this is not a huge improvement. CX is the prime gripe for many people, and that is the problem that needs solving. It will be great you could consider this.

For example searching for SEA-HKG on AS+ ( CX) will be a lot more helpful than say, trying all CX routes from NAmerica to HKG and piecing together with an AS flight.
