I've stuck with QF through all their "enhancements" but I think this is the end.
I'd have to agree. These changes, especially to the partner SC earn, is likely the last straw. It's just a matter of finding another oneworld program that fits my travel habits.
To date, I've booked QF codes whenever possible.
Where a QF code hasn't been available, I've booked towards what would get me the most points, generally an AA code.
Then I book whatever code gives me the best result for taxes etc.
If QF wants me to continue booking QF codes, then they need to explain how I can fly ICN/NRT/HKG-SFO/LAX/YVR/DFW/ORD/JFK/YYZ or North America-Europe with a QF code (more useful Europe-Asia QF codes would be nice too).
I had been working on my holiday plans for this year (normally DAS13+DONE3) while trying to benefit QF as much as possible. The delay with announcing the new QF9/10 timings slowed that planning down. This program change has put a complete halt to it.
As for status matching...
AA said to call AAdvantage.
AY said no.
It appears that CX will consider it if you email them a copy of your Activity Statement.
Haven't heard back from MH or BA.
