Flying AF marketed AF - delta miles?
Hello, I have an upcoming multi-stop international trip on AF marketed by AF and stand to earn about 19k MQM and probably 38k miles on this trip by delta's program, as I am flying premium economy on the a380 (first time)
1) should I register to become a flying blue member? Would I earn MQM/mileage on both airlines? I don't want to lose out on what I would earn from delta.
2) I hear AF offers upgrades for discounted cash 7 days before flight? Anyone know anything about this? My first flight is lax to cdg, I.e. I would love to upgrade to business from pe...or any other advice on how best to do this?
Thanks in advance
