Thank you everyone! Sorry for the lack of details. This is for Scandinavian Airlines (SAS). The itinerary includes the whole family, so it is all on one ticket. I have done some additional research, and there seems to be two other flights to GDN on that day. The second flight of the day is at 1PM, and the last flight is at 10PM. The flight to CPH originates from Newark (EWR).

Also, where do the passengers unload from the aircraft (closest seat number)? Based on the flight info, this is likely the aircraft (Airbus A330-300 [333])used:
