I may move my ST FF activity to CO (it's already a secondary program for Chase and rental cars and stuff). I'm flying CO more and more anyway, and the EWR-HNL shuttle

is my most common flight, so...
OTOH, if CO gets swallowed up by UA, I don't know what I'll do at that point. I can't imagine abandoning ST completely, as I fly to ST hubs and focus cities quite a bit, and I LOVE transferring at AMS over FRA or (gasp!) LHR.
Maybe I'll just quit flying, and have the world come to me.
Or become wealthy and fly full juju and to heck with FFPs - they're for the masses.
