I purchased miles for a round trip from Cincinnati to Berlin in BUSINESS CLASS. I was seated in economy class from Cincinnati to Washington Dulles. And the same will happen when I fly on my return from Newark to Cincinnati. When I asked why I was seated in "the lowest" economy class, I was told I could upgrade to a higher economy class if I pay extra. I flew business class on Lufthansa from Frankfurt to Berlin on the same itinerary. Why do I have to pay extra when I purchased a business class ticket already? I have flown many times on American Airlines, purchasing miles. I never ever had this problem. with them.
