The OP needs to read this thread:

Delta Upgrade Certificate Availability Confusion (KLM Operated)

I had similar problems where I believe there should be some way to upgrade all segments in an itinerary when Z is available via married segments and OP is available on DL operated flights. However, hours on the phone with DL and asking FT did not get me anywhere.
What I posted was NOT incorrect, it was Z availability on KLM flights only, not DL flights. You cannot search for JFK-AMS and AMS-CPT separately, you need to search JFK-CPT on KLM to see true Z availability.
