I am booked on a CRTWSTAR ticket for later this month and I wanted to change one of my sectors, that being the DXB-BKK with TG. I wanted to push it back one day to 9th July but its telling me no availability.

Is there any chance D Class, which currently shows 0, will re open as their seems to be quite a few seats left in C?

Or am I fresh out of luck?

I dont really want to change the routing due to the fees. My following sectors are BKK-SIN and SIN-MEL.

Thanks
