EY has been demoted to a minor/secondary partner as a result of the QR partnership though.
They're at the same 'status' as the fellow secondary partners that are the HNA Chinese Carriers, SA and VS. The secondaries are 'still' only in VFF primarily as redemption options.
You can redeem on EY, however if you do a standard booking ex-Australia (via points or cash) the booking engine mostly prioritises the QR codeshares as VA's primary partner.
