I am looking to fly some staff to Europe from Taiwan and use some of the hundred of thousands of miles I have to upgrade them to business class. On line at CX website it says economy fare is 32000 NT$ but travel agent is saying we have to buy a fare at 59000 to upgrade them. I never fly economy class so have no idea about fare rules but I wonder from those of you that do can you offer me some advise on whether to find another travel agent or if I can book online and upgrade them later.

Thanks in advance.
