As my offer was not destination specific I assumed it would have been a generic one.
As a data point, I am in my 2nd month of the qualification year, have 300SCs so 900SCs to requalify for platinum, have flown only BA so no QF flights this year, went on QFF website to check SC creditting but have made no dummy bookings, my account is listed in UK currently.
My offer came in on Monday morning, headlined "Fly to Brisbane, 50% more status credits" but the text of the email is not destination specific, so I am unsure what will happen. Book until Dec 3, travel Nov 27 to Mar 27, 2018. As a further data point:
current status: Gold (for four or five years, always just scraping in with slightly more than the required 600 SCs)
membership year ends Sep 30, 2018
currently on 395 SCs, with only one forward booking, a Y family trip to Europe on EK (QF codeshare flights), so no real hope of making Platinum unless I do a status run.
As I needed to book flights for the first quarter 2018 anyway and pricing to Perth and Brisbane was acceptable, I made a few bookings and it will be interesting if I get bonus SCs for the Brisbane flights only, or for all.
On another note, the week before that I received an offer for double points for bookings to China, including HK. Haven't been there since 2015 but used to go annually, no idea why I was selected for this promotion. Did not book.
