Would that be
- AA Gold Status
- BA Gold status
- QF Gold status
- ...

They are all different
- AA Gold ranks as Oneworld Ruby status
- BA Gold ranks as Oneworld Sapphire, or is it Emerald, I'm not sure
- QF Gold ranks as Oneworld Sapphire

There is no alliance-wide Gold status
Status in a member's FFP can be equivalent to Oneworld Ruby, Sapphire or Emerald (or nothing)
