*A is my secondary network after OneWorld. I used to use AC because a) I was on the boards of 2 Canadian companies; and b) my wife is Canadian and so we visit family there, but they upped the minimum threshhold for *G a few years ago and I switched to A3. It looks like I've had 65K miles since May 2013. Some of that is from BOS-IAH and BOS-DEN and some LH flights. Much of the domestic is refundable coach and the international is business class. I haven't flown on SQ since they eliminated the SQ-EWR flight. Some is on USAir flights which now would be on OneWorld.

I'm thinking I will have to switch from A3 given their changes as I don't typically fly to Greece. My priority has been getting domestic (and sometimes international) lounge access and boarding priority. Miles matter less as I have 1 MM Avios and 1.7 MM Membership Reward Points. So, I find it harder to spend my FF pesos than to acquire them.

Which would be the best program now?
