Sorry, but just for clarification, does this mean a DL Elite will get put on the upgrade list on ALL Northwest flights or only those that are code-share flights?
Is there a way to tell before you buy the flight on either DL.com or NWA.com that the flight is a code-share?
Lastly, does this all mean that for a DL-Elite (like myself) we should only be buying Northwest flights via DL.com and not on NWA.com?
Thanks.
