Enter your nearest departure city and CPH, then pick round-trip dates in September or October — those two months had by far the widest award space.
Once results load, switch to Price Calendar. It shows a full month of award pricing at once and is the fastest way to spot the 27K–38K dates.
If you want a nonstop, filter results to Nonstop — only Minneapolis and New York offered one.
