I was to fly BKK-CMB-HKG on 4/22, the first day the flights resumed. I was concerned about these flights and called CX beforehand, and they told me then that if the flights didn't go I was protected. Of course, look how things can change in 10 days.....

Best to work out with RTW desk - maybe they can accomodate you and do routing change without a fee since it is involuntary.
