Recently relocated to Australia and trying to figure this out. I've searched the forum but can only find info on BAEC and AA flight upgrades or QF upgrades with QF program.
Recently I flew from SIN - SYD. Economy ticket but decided to upgrade to Business in the lounge. BAEC credited with the business class tier points and miles

Happy days even though when I asked in the lounge I was told no it would be economy points. So this got me thinking...
Now, I'm flying to PER and wondering if I should use the Bid Now option? I know Qantas say that you don't get enhanced tier points/status credits in the T&Cs but will BA still credit?
Should I remove my FF number rather and retro claim?
Or rather chance a paid upgrade at the airport?
Any info is welcomed
