If they do get to use the SAA lounge in Cape Town - it's very nice.
Split into two sections, one for 1st class and the rest for business. Usual facilities - showers, bar, TV etc. Loads of seats and a children's play area. PCs are available but the internet took ages to load up. food wise it wasn't so hot - sandwiches, crisps and biscuits.
Staff very friendly and willing to help too. See
linkAirport is modern, enough shops and cafes to keep you occupied and the main waiting area overlooks the apron and runway!
BTW - I'd love to know the full details about the reciprocal FF programme - I've got loads of Voyager points that I just have to use
