What exactly is the written rule about this?
I also changed dates on a CX ticket before the first flights, not changing the date of the first flight. CX-Japan said the ticket had to be reissued. Fortunately the base price had not changed.
I pointed out the written rules and received the following response (all arrangements were by e-mail):
From the next step, we need to reissue your Oneworld explorer ticket.
As xxxxxx informed you before, your ticket is totally unused since we have issued, so we need to check all Airline carriers fuel surcharges and each airports taxes have been changed or not.
If there is any tax/fuel have been changed, we will let you know and we need to reissue your ticket to collect or refund the amount.
I had to pay a bit more in fuel/taxes and a JPY3,000 service fee to reissue the ticket.
