I was supposed to call this morning, but forgot. I will call to make the move tomorrow because we are going to fly to Hamburg via CPH on SAS since it will arrive faster than TK to CPH. The flight leaves one day earlier and arrives nearly 6 hours earlier (4PM instead of 10PM), we will be able to spend a few hours walking in Hamburg before we shut down for the night. My original flight didn't have the stopover, I am not sure if they will allow us to push the flight to the next day on TK.
The weird thing about this flight is that it is available on Aeroplan, but not United or Lifemiles. I wonder if it is true availability or phantom space
