Can someone clarify a question for me (have been unable to find this via searching).

I will be flying on a oneworld flight in International First Class. If I don't like that airline's lounge, can I use another oneworld lounge in the same terminal? Star have this policy but not sure about oneworld (their website wasn't of help either). I don't have status on oneworld .. so don't know if that will make a difference ...

Thanks in advance for your assistance
