I agree with the thought that Classic Plus overall is good for those non-AFF types who are happy with the compromise in burning their points, leaving the Classic Rewards available for those like ourselves who can put more time and effort into finding them.
Obviously, partner airline availability isn't affected by the presence of Classic Plus or not, and Qantas maintains that they'll keep the number of their own Classic Rewards on their own metal the same (for now), so overall, there is a net benefit.
It would be a fixed rate if the ever-increasing taxes were covered, but they're not, so depending on the route it could be quite a bit less.
Classic Plus's fixed rate takes into account taxes. The points total is adjusted, so it's always 1.0/1.5 cents per point after the tax is subtracted from the underlying cash fare.
Qantas (and the websites who are advertising for them) love promoting the odd example of it being cheaper.
But in these cases you might as well just buy a cash fare (and earn points/status) rather than trading in your points for 1c each - I guess they are assuming people won't be smart enough to work this out.
The odd example of it being cheaper is handy for those who do want to save money and use their points for a trip. Yes, you could (and I would) book the cash fare if it's that cheap and you want to save points/earn SCs.
But it also comes with more restrictions and no upgradeability (assuming Economy Sale) so there is a place for Classic Plus connected to a sale fare for those 'standard folk' who have been saving for a while and can now get a family holiday with low co-payments, Points Club/status members who want to upgrade or those who prefer having the flexibility to cancel for 6K points.
I would argue that websites such as PH should be highlighting these rare nuggets as it
is a points saving for a specific group of people. Of course, for the other group of people like us, there are still
actual reward seats being found and shared.
