Moving from *A to SkyTeam.
I'm about to move to Paris. I've been a LH SEN for ever, but I guess I may be using AF now a lot from CDG for long haul. I have a Delta account (with the original card from 1988), so the question is: should I carry on using my SkyMiles account or get a brand new Flying Blue account? Or... Carry on flying LH etc as much as possible?
