Yep. Got the email last week:
Dear astrosly
Booking Reference: XXXXXX
We would like to inform you that the flight number for your booking on Qantas codeshare flight operated by Emirates between Dubai and Milan has changed.
You will now be travelling on the same service but with an Emirates flight number.
This means you will travel as an Emirates passenger with an Emirates flight number for the sector between Dubai and Milan, rather than a Qantas passenger. All other details of your flight – date, departure time, travel class and inflight product - remain unchanged.
Qantas Frequent Flyer members booked to travel on a Qantas codeshare service between Dubai and Milan who are rebooked onto the Emirates flight number will earn the same Qantas Points and Status credits for their flight.
You will receive a new e-ticket itinerary receipt noting the change of flight number prior to your departure.
If you have any questions or require further information, please call Qantas on 13 13 13.
Regards
The Qantas Team
I had actually noticed the week before when I was checking the seat assignments but the booking had been locked to changes and when I called they confirmed that FCO codeshares have been removed as well.
