Here's another example of creative yield management. Check out the CO flights from NRT to SIN, which are codeshares actually operated by NW. I was trying to get a flight on CO from IAH-NRT-SIN, and it seemed that the NRT-SIN segment was always sold out (Y0, let alone K0, etc.).

But, they are sold out only if you are connecting with a trans-pacific flight operated by CO. If you connect with a trans-pacific flight operated by NW, then the NRT-SIN segment magically almost always has inventory available. This is true even if the NW trans-pacific flight is ticketed under the CO codeshare.

The above behavior I can see through ITN has been confirmed as the same that CO ticket agents see in their computers, so it's not just an ITN quirk.

The NRT-SIN segment on NW must be in high demand, as it is fed by all of the NRT flights from North America, plus the Continental ones. NW must want to avoid having all of the seats on these flights taken by CO customers, which would prevent ticketing their own passengers on this connecting flight. This, I understand. What is amazing to me is that all of the CRS's apparently have support for just this situation, which leads me to believe that it's more common than we think.
