Emirates Skywards - Change from 2 class to 3 class 777-300er

My flight next week was booked in j on 2 class 777-300er. in my booking it is now a 3 class. does anyone know when and how to get the row one and two seats. i have seen on here that it will be operated as j-y. is it at online or at the checking desk that they let these seats go. any info on this would be great.
Many thanks

I think at check in. They would usually assign the seats to Gold and Silvers first, but if space is available and you ask, you can get your seat reassigned there or in the lounge.

The Wife & I are both gold members, so we will wait and see. Many thanks for the Info:cool:

But a word to the wise, I have been on flights like this where the fron cabin has been left empty for the duration !
