I am wondering which ff program would be best for consolidating miles on for someone who just does an occasional flight on skyteam flights. I overwhelmingly fly *A, but I have a couple flights coming up on Alitalia and Alaska so I'd like a place to park those miles. I'm leaning towards CO after reading up on all three, but it's hard to determine from their which would be best. It's unlikely I would obtain anything more than a 25k mile status at best, so I'm wondering which would be best for an occasional award ticket and lower end status.
