I'm planning a trip to HKG from MEL in J later this year and want to know, if i purchase the ticket thru a 3rd party website (expedia), am i still able to earn QFF points & status credits if i give them my details?

Yes. The rates will be dependent on the booking class though.

Yes, as long as you put in your QFF number in the booking details

Yes - worth being aware of. My expedia flights were approx $100 cheaper than on the airline website, but some were in lower earning buckets than if booked through the airline. Was half the points on some sectors.  

Thanks Michael, very interesting you say that as expedia were quoting a few hundred less than thru the airline website. Might have to look into that
