Thanks, OP!
I booked something similar to this through the AMEX program:
Instead of paying $1,713 I used the AMEX IAP to pay only $1,443. I had to try the online AMEX travel booking site multiple times. I got errors, and my first successful booking changed my routing from AMS to JFK. But I persisted and eventually I got what I wanted. Took about one hour to try different little minor changes with my flights. I had my dates all picked out from using the Matrix.
I ended up with: All KLM flights; direct from Las Vegas to Amsterdam on a 787 both directions. I could not book a long layover in AMS like in the picture above.
I expect 17,568 MQMs since this is 150% of the distance. This works out to $0.082 USD per MQM.
This is the first deal I have found to Europe! I got two tickets... my wife is going with me to Brussels. Thanks again, OP!
