Where to Credit Qatar Flight - Qantas Frequent Flyer or Qatar Qmiles?

I will be flying Business with Qatar from Adelaide to London return and I dont know which is the better way to go with earning points. Do I book and give my QFF Number and earn some Qantas points or should I sign up to Qatar Frequent Flyer and earn Qatar points which might get me a good status level which can be used when flying with Qantas? I am currently Qantas Silver, so was planning to use my Qantas FF to get Qantas points. Any help appreciated. Thanks

Personally, I would credit to Qantas unless you plan to fly predominantly Qatar Airways in the future. They share the same oneworld benefits. Unless you find a Qatar specific benefit that you can’t get with Qantas status, which you desire.

1stly, you already have Qantas Silver. Your return flight will only get you Qatar Silver if you start from scratch.

Miles (status) awarded for your return flight:

If credited to Qatar-> 25700-41120 (150)

If credited to Qantas-> 20000 (240)

You can have a better look at Qatar Privilege program to compare with Qantas FF.
