I just so happened to be casually looking for JFK-BRU Business Class award space on Brussels Airlines because that’s what Saturday mornings are for, right?
I was able to find a Business Class award seat on the JFK or EWR to BRU route nearly every day in May and June 2017 (with a few dates in March and April, too).
The reason I’ve had my eye on this award is because Citi ThankYou points transfer 1:1 to Etihad Guest miles. And Etihad has a very generous award chart on this particular route.
A round-trip ticket in Business Class costs just 36,620 Etihad Guest miles. Of course, you have to transfer in increments of 1,000, so realistically this will cost 37,000 Citi ThankYou points. Which is a steal.
United would charge 70K miles each way, or 140,000 miles, round-trip. So you’ll save a huge number of points by booking through Etihad instead.
