Is anyone else still waiting for credits
All the credits should now be sorted. What date was the flight?
or should I be chasing them up now?
I'd be chasing them up now. You should have received an email with the new details, perhaps search your inbox for the subject "Your Future Flight credit" otherwise call again.
Whilst the following won't help you access the credit you might be able to check if it exists using the process below: If you had a velocity number in the booking then you can check if the credit was initially converted to a future flight credit by looking at your travel bank linked to the primary passenger's velocity account. The easiest way to access this page is on the main website
https://www.virginaustralia.com/au/en/, login to velocity, and make sure you're at the old looking site (looks like the page below) if not scroll down and click "Visit Accessible Site".
Then perform a random search any destination/date will do and you should see the following on the side with the ability to click on "View your travel bank details".
It should load the travel bank and you can click on "Account Statement" to see the transactions. Everyone had their credit dropped into their velocity travel bank for a few days before being converted to a future flight credit.
For mine, the first entry was the 9th of October as the refund and then on the 17th of October the transfer to the future flight credit.
I presume I'll eventually get a credit in equivalent AUD (no doubt at an exchange rate favourable to Bain!)
Yep, all credits from the New Zealand flights in Australian dollars. On the 9th of October mine was converted at a rate of 0.9236 NZD to 1 AUD. Whilst it's not a bad exchange rate, given XE/Google lists the exchange rate on the 9th as 0.9212 NZD to AUD it's actually more favorable than the rate I can see for that day.
