I have flown 1st leg of my RTW (ICN - NRT) in business already, my next flight will be 27 July (Mon) NRT - HKG on CX. Today (Sat) I called CX Tokyo to change to an earlier flight on 27 July but they asked for a fee of US39 (?) because my RTW ticket was issued by Qantas. Then I called Qantas Tokyo and their office is closed for the weekend.
I very seldom fly RTW on Oneworld and I have no such problem with all my Star RTW tickets. The changing fee is not much but is it correct that I have to pay?
