Hi all,
It looks like I have to fly BA quite soon. Therefore, I might as well pick a OW FFP to join, although I already have cards on *A and Skyteam. The question is, which one to pick.

I won't be using OW too much, but will probably use *A,Skyteam and OW in future, in that order. So which OW program is easiest to 'keep alive', and easiest to get a reward from? I'm leaning against Quantas, since they seem to have good collaboration with both *A and Skyteam members, but I would be interested in thoughts from ppl using OW extensively.
