Well, there ya go. Egg on my face...
If you after Status in Staralliance, you may think about Aegean Airlines.
If you chose the right booking classes, you may be Star Gold with one trip to Asia!
You may think about the Airberlin Program. You will earn Statusmiles on every Oneworld flight plus on Etihad. Maybe that will be a solution.
As a member based in Europe, I find the 4 Segments quite harsh.
I started about 10 years ago. The main Argument was the Lifetime Status (and is still).
For my EU Trips I use BA in Club Europe - so QF does not pay for my lounge access. They earn a little amount with my points.
Under the old rules, BA Gold would have been more easy to attain than QF Plat, but I still sticked to QF!
I still manage to do a flight to SIN every year to get my four segments (with codeshare feeders), but I really give them some revenue.
But on my Australia trips (not regulary) I usually fly quite a lot - sometimes with quite significant groups. I would never consider DJ.
How loyal are the people that fly 4 Segments with dirty cheap Red E-Deals or Jetstar fares plus some AA runs? More loyal than a guest that books a F-Ticket LHR-SYD once a year - who just gets two segments? How loyal is someone who books the QF Flights LHR-SIN with the BA code (same amount of revenue, due to revenue sharing) and flies that in F or J?
I see the 4 Segment rule just a discrimination of oversea users, as QF is just reducing their international network. If you live outside Australia they do not care about you. End of Story!
On one hand QF complains that their international network is not making money. But they make it very hard to be loyal with them!
