Keep in mind that CPH-ORD was left operating pretty much daily throughout the emptiest days of the airports during the pandemic. Cargo alone is what supported my being one of sub-20 passengers on a lot of those SAS flights. MSP won’t fly for cargo like ORD. DTW? I doubt it flies well for CPH. Chicago is a way more important business center than MSP and even DTW, and as DL@ATL has found out before with service to Scandinavia, connecting at ATL wasn’t high on the order for Scandinavian and Scandinavian-bound travelers.
CPH-JFK replacing CPH-EWR flights would be just fine by me if it weren’t to likely mean worse ticket costs for me when flying SAS and onward within the US after the SAS TATL flights. But I foresee it coming with higher ticket costs for me, and that I won’t welcome.
