Done!!

Just wanted to come back and say thanks to this forum, I would not have figured this out on my own. I used Chase/Visa/United miles to get one way BOS-BRU business class, and Amex rewards points transferred to a newly established Flying Blue account and got business class nonstop AMS-BOS on the return for 50k miles/pts.

I was skeptical and nervous about transferring the miles to flying blue. But I got to the site at 12:01 the day they released the seats and got the pick of the cabin for seats. Non stop return with excellent times. $307 in fees but I can take that.

Just need to figure out how to get from Antwerp area to AMS/Schipol the day of the return flight, but I have a year to figure that out......!
