AMEX has been offering a 40% bonus on transfers of Membership Rewards points to Avios, but that is ending tomorrow!
I’ve used Avios to book several trips recently, mostly exploiting how short haul award tickets are only 4500 Avios each way! I’ve booked several tickets to Chicago for the fall from DC, but I also used Avios to book Cathay Business from YVR to JFK for my Xmas travel. One Mile at a Time has a full rundown of these redemption options as well as a few others on Avios. I am probably going to transfer a chunk of points to Avios before this ends, just to have them for future trips.
