We are currently travelling in both South Africa and Zimbabwe. Our flights between JNB and VFA were on SA in business and we checked out the Aspire prior to our departure from JNB and it is a decent sized lounge and when we were there (around 10:00 AM) it was not crowded. A decent buffet breakfast, including a good grind, brew, dispenses espresso machine. The seating is comfortable, with adequate access to power outlets. I thought the Aspire lounge was well above average, but we also had access to the recently remodeled SA international business lounge and is was much better than the Aspire.

We'll be departing JNB in about 9 days and will check out the Bidvest Premiere as well as the 27 Lounge. I had seen that the JNB lounge for EY flyers in JNB was the 27 lounge, according to the EY website. I'll post back with my impression after we get back.
