Thanks. That may be the problem. The fare class Sydney to Perth was described as "V" when the ticket reached me four days after I booked it. There is no warning of this downgrade on Air New Zealand's website and the box which you highlighted in red did not appear on my ticket. Do you know if this is a recent addition? At best, this is deceptive advertising and at worst, it is breach of contract. Another galling factor is that I could have bought a guaranteed business class ticket with Virgin via Melbourne for $100 less.
