NW has so far steadfastly refused to participate in any of this EQM nonsense with CO or DL by downgrading its own program (it does restrict EQM for customers flying discounted CO metal flights, but all DL fares earn full NW EQM). My guess is this policy will not change, Skyteam or no Skyteam. NWA is the only airline of that whole bunch that still its common sense and customer-oriented attitudes intact.
