Grrr...I tried clearing my redemption list today. Entries made OK, card successfully entered, VbV correctly keyed in and acknowledged by bank, then return to cathaypacific.com for this:

"Due to internal system error, you are unable to proceed further. Please close the current browser and try again."

And the list *has not* been updated.

Fire up another browser, repeat, OK. But bank has confirmed double authorisation, so I'm going to have to keep an eye on my bank statement to see if CX posted first charge.
