There's a misconception in this thread that a move to revenue-based earning will empty out the lounges, decimate the elite ranks & end gaming behaviour.
It doesn't do any of that. Instead, it switches the cohort that attains elite status, fills the lounges & games the program. The program switches from rewarding the person able to game status runs to rewarding the person able to game the airline's on-the-ground partners.
To take a simple example, if you want to earn elite status cheaply and easily on Qantas, your best bet is to status run on Qantas and partner airlines.
If you want to earn elite status cheaply and easily on a US airline, your best bet is to game its credit card and shopping portal partners.
To give just one example, in 2024 my partner and I earned over 500,000 Loyalty Points (well in excess of what's required for both of us to acquire the AA equivalent of Platinum One) at $0 cost and without crediting a single flight to American. All through gaming. This happens all the time in the US.
It'll also happen with BA. There is going to be even more gaming of the holiday package program than currently occurs. Not to mention the gaming of the TPs you'll earn from credit card spend.
It'll happen with Qantas once it switches as well. We saw a sneak preview of it last year with the
Qantas holiday promotion where you could earn 5K points with any stay. People exploited it by booking $2 Bali stays. But instead of just earning points, under the new scheme you'll also earn status by taking advantage of these loopholes.
Importantly, the very best loopholes are not shared in public because they get shut down if they hit critical mass. So what I'm mentioning is really just the tip of the iceberg.
Airlines need these on-the-ground partners because they are the main way for their loyalty businesses to grow.
