On January 29, I am flying on CX 722 from KUL - HKG. The res. agent informs me that it will be a 340 that day. Since I'm on a F rtw ticket, I was happy as normally you can only get C on this sector. She shoots me down with no this aircraft is configured only with C.

I think that what is really happening is that they are using a larger aircraft due to the heavy traffic with Chinese New Years, and they are simply selling the F section as C.

Does anybody know for sure?
