Is there a way i can use my delta skymiles on air france website to get a one-way for half the price of roundtrip? I heard that it was the only way to get it and i know i could transfer amex membership awards to flying blue miles, but I don't believe I have any. I do have a delta gold amex, but i think I only get delta miles with that, not membership awards. I am trying to go to chile on delta the end of January and my aadvantage and united bonus credit card miles won't be posted til 3o days after billing date they say, that's too late for me. Anybody have experience with this? thanks!
