I am sorry if I missed something, but what makes us believe that upgrades will be possible on one's airlines codeshare flights (i.e. DL) on different metal (i.e. NW or CO)? I am not aware this is possible when flying with any SkyTeam member (except the famous exception when flying AF on Delta codeshare transatlantic). </font>
Flying_Duck....I regularly fly DL codeshare flights on AeroMexico and am treated the same as I am on DL domestic routes. Upgrades 100% of the time, etc. This is ideally the way an alliance is supposed to work. And, IMO, so far, so good.
