Booked CO flights from AMS to EWR in I (cheapest) yesterday - obtained ticket numbers by phone.
Called FD Helpdesk immediately to arrange upgrades on miles - in process.
At the end of the afternoon the travel agent called me to say that she noticed we already received the upgrade. With the PNR I was able to choose seats on the CO website. Today the FD helpdesk confirmed the upgrade and said they will mail the vouchers.
If the flight works out this must be an upgrade speed record.
Best
