AZ: AMS-MOW in J for €435 RT (BRU, DUS and others departure possible as well)
Transfer: FCO, MXP/LIN
I'm booking it for the second time this summer (last time a month ago). Thought it was an error fare, but it doesn't seem to be so since it's still available.
The nicest thing is the Italy(FCO/MXP) to SVO sector (and back): you can opt for a SU-operated flight which has a proper hard J product with 2-2 configuration and excellent service.
Even though AZ service on AMS-FCO sector normally sucks their lasagna is delicious! So the whole trip worths it.
Books in D which gives 200% miles in Flying Blue (the FFP I use, check for yourself about Delta, etc.).
For me, a Russian expat in Amsterdam is just freaking perfect.
