Agreed. Without a BA transfer bonus, MR transfers to AP make the most sense. For a short while, you could transfer them for a 16% loss to US through points.com. But with the historic United deval of 2013, AP now has the inside track on *A premium cabin redemptions. As I implied in my post above, I plan on using my Aeros for TK Biz redemptions.

What makes an SPG transfer tempting, though, is to hedge against an AP deval, which is always a possibility without warning. You know your SPG points will always be worth a lot.
