I need some advice. I have over 150,000 freq flier miles saved up in Delta. I want to fly from San Francsico to Berlin (and back) next year. I'm seeing that it costs over 90,000 miles. But you only need 60000 miles for a roundtrip flight to London. Does it make sense to fly to London and pay for a flight to Berlin in order to save 30,000 miles? I tried other places in Europe with Delta and they all seem to cost over 90k miles except for some places like Paris (77,000). Am I missing something? Why is it so high to go to Germany? Thank you.
