I am on an award ticket on Emirates F booked through Qantas. If I manage my reservation on the Qantas side, it gives me an option to add DC; but managing my booking on Emirates the option does not appear. I added DC through Qantas and then proceeded to email the itinerary to myself from the Emirates website and the itinerary shows the following:

Stopover City: Dubai
Check in: 02 Sep 19
Check out: 03 Sep 19
Remarks: 3SEP STPC-FIRST AND BUSINESS ROOMS-1
Status: Confirmed

I wonder how valid this DC is considering it was offered through Qantas and not Emirates website.
