I have a 12:07 departure scan as well.
I looked through Incheon departures and the only freight flight coming into Europe around the departure scan time is flight KAL509
Unless its on a scheduled flight? There appears to be a Korean airlines flight direct to Heathrow landing at 17.15 but I am sure I will get an update later?

It seems yours is on the plane now and arrives in about two hours.
I can only assume you have a UPS number because it is being delivered by them?
Thats what my delivery note has down as carrier. I had a superdrive ordered but cancelled that, so nothing has to be merged before coming out to me.
