Hello, just quick question from a newbie that I hope you can help me with. I`m currently a Flying Blue card holder and I`m looking to fly NRT-ICN in the near future on Northwest.

Do Northwest flights all earn 100% of the miles? I think 500 miles? or like KLM/Air France nonsense, certain tickets only earn 25% depending on the class? If so, what classes earn 100% miles?

Thank you

I did a search but couldnt find my answer. Apologies if it`s a repeat question
