Have been following this thread as we have reward 2 4 1 flights booked in J (F not available) to AUH 30th Oct out and 9th Nov back. 4 weeks ago outbound plane was changed to 4 class 777 and we were able to upgrade with avios to F so quite happy, CCR here we come. Checked this morning and outbound flight was cancelled and replaced by the Air Belgium flight and we were downgraded to J, seats 1A and 1C. No email notification received, Called the gold line and was told that we will be refunded avios and fees for upgrade and can still use CCR. Asked about inbound flight, which at the moment it is unchanged, but they could not say definitely that it would remain so. Was told that currently outbound flights were affected up to the end of October and inbound to Nov 2.
