KLM agents actually have a fare bucket list for both Delta and KLM fares that tells them what the upgrade fare is. It runs from 100Euros to 400Euros.

I recently upgraded from a T fare into BE for a 300Euro fee while on a Delta ticket and Delta metal, amazing.

So what I am curious about is, have others seen this and more importantly if KLM can upgrade me on a Delta ticket and Delta metal why can't / won't delta do it?

I recently called Delta about this issue and they indicated that upgrading from low fares was absolutely not possible and they stated KLM could also not do this.

Interested to see if others have experience with this?
