Sky Team Upgrades
I was formerly a Worldperks member but as of about a month ago I am now Gold on Delta. I am currently living in Norway so I am constantly starting my international travel here and transferring in Amsterdam. I have never been upgraded on any itinerary from Norway. Upon reserving seats on Delta.com for an upcoming trip I realized that it says I am not "eligible" for upgrades. I am assuming that this is because I am traveling on KLM operated flights. The trans-continental flights usually have a DL or NWA flight number in addition to KLM but I check in on KLM on the short flight from Norway to AMS. Is there anyway around this so I could be eligible for upgrades on these itineraries starting from Norway? Maybe in my situation I should switch to flying blue.
