I'll be doing BOS-JFK-JNB-CPT in a few days and having recently acquired *Gold status, I was hoping to make use of the Swiss Lounge in Terminal 4. My flight will get in at 8h47 though, so I was wondering whether the lounge would be open then. I can't find anything online, except for their Zurich ones and presumably the lounge does not operate from 6am like those.

Thanks,
