Answer
'To claim Velocity Points for eligible flights with Etihad Airways, Delta Air Lines, Virgin Atlantic, Virgin America, Hawaiian Airlines, Air PNG or SkyWest email a copy of your Electronic Ticket or Boarding Pass to
[email protected]. '
Back when I claimed 15 weeks it ago, Air NZ was on that list.
I just found out a couple of days ago, AIR NZ no longer is... helfpully, they also aren't on the list of the other airlines that you can do retrospective claims for.. ('Claim missing Points for flights on Virgin Australia, Virgin Samoa or our other Airline Partners.') - other airlines seem to refer to the list above starting with Etihad - or to the other Virgin branded ones (and poly blue).
Clearly this means the other advice must be followed..
'For flights with Virgin Australia, V Australia, Pacific Blue and Polynesian Blue and our international airline partners ... Please have the following handy to claim you Points:
• Your membership number.
• For flights, your flight booking reference (PNR) or flight number, date of flight, origin and destination (if unsure, call the airline and they should be able to help).'
So I sent in my boarding pass when it told me - met requirement #1.
I've definitely sent in date of flight, origin, destination, flight number (all on boarding pass!) - met alternative requirement #2
But guess what, the 'details I submitted' were wrong.
What an utter joke this whole program is.
