Insights shared by verified travellers who flew the route from Boston to Copenhagen

Check with the airline and validate that all of the advertised benefits are indeed available. Paying higher price for the Economy Plus tickets may not be worth it for you as a number of advertised benefits are not available, definitely not in Boston
JonFlew with Scandinavian AirlinesBOS-CPHJun 2024
Be prepared for a possibly short layover between flights. Mine was only 45 minutes and needed most of that time to clear passport control and get across the airport. That said - it seemed that the SAS crews were used to that. On the plus side there was no waiting in the terminal.
