Hi

I have an avios + companion voucher booking (SIN in F) that was originally booked in June 2020, for June 2021 travel (i.e. T-355). The original flight was cancelled in ~May 2021 and I opted to rebook for dates in August 2021 (without there needing have been avios availability for the new flights). The August outbound flight has now been cancelled and I wish to move the flights again.

Will I be able to do so given we are already past original booking +365 days? What restrictions/parameters am I operating in here?

Thanks
