It appears that NW codeshares on YX routes will only appear where NW does not provide ns service itself.
If YX doesn't have the ability to make sure all of their flights show up on travel sites such as Expedia, it will only hurt the bottom line. The NW/YX partnership was supposed to benefit both carriers, and not hurt YX.
