Earn AF miles or DL miles?
So I got cheap air tickets to CDG by AF, and the booking class is N which means I earn 25%x2=50% (FB Platinum).
I'm based in the US, and I'm not sure if I should credit those miles to DL.
I know I can earn 100% miles from DL, but I also heard that it's hard to use DL miles...
What about AF?
Also, if I want to earn DL miles instead of AF, how can I do that?
I'm a *A guy, and I don't know anything about ST... I got the FB Platinum status by status match this year.
