FF Difference? KE or DL
I'm planning on taking a trip to LAX-SGN on Korea Air. I know Delta and Korea Air are part of Star Team so either way I'll some mileage for FF out of this trip if I provide one FF membership number, right? So I'm wondering if the experts can chime in whether it's better to get a FF on KE or DL? I don't fly either one very often. Most of my trips are MHT (manchester, nh) to lax area.
Thanks in advance.
