Hi All, I am based in Sydney,
I am in the process of booking flight from SYD- LHR,
Question 1:
I want to book the SYD- HKG -LHR, knowing SYD-HKG is operated by CX but has a BA code, can i consider this as an Eligible flight?

Question 2:
i wanna book the return journey straight with BA,
on the website it says LHR-SYD one stop and doesn't indicate where is the stop and also the whole trip only has one flight number BA015
i am curious to know if this whole trip consider as one eligible flight or two, given it has a stop in the middle.

i have accumulated enough points to retain the gold, i need 4 eligible flights to reach the gold status next year,

please if anyone can kindly answer my questions much appreciated.
