Due to some unusual travel this year I have the ability to achieve BA Gold status if I want to. I'll have to do a sort of MR (a trip I want to do but not one I need to do). I'm intrigued about achieving Gold as it will give me all of 2014 at Gold and a soft landing to Silver for 2015. Going forward I'm probably only going to do 1-2 flights per year on BA and I already have silver. Most of my flying is on American domestically. The $1500 MR isn't worth it to me for the BA status, but is it worth it for Emerald OneWorld? Outside of priority checkin/boarding/checked bags... does Emerald actually lead to free upgrades on American? Any other benefits I'm missing?
