had a problem with my ticket so I had to call eServices instead of local reservations team. The server timed out but bank said the charge went through, waiting for the cancelation to book again, the good thing is CX will hold the reservation and fare until that happens. :-)
Called today I was able to ask for the 5pm flight out of PVG and get CX903 from HKG to Manila on the 21st instead. I just have to pay 15 dollars as HKIA airport fee. I think that was pretty painless...
