Andi:
I am almost positive that we are on Nationwide. I don't know what class we are booked; you need to check with one of the Princesses or Ngaire. Looking at current prices for that day, Economy is 2710 Rand while Business is 4710 Rand. So, the difference is around $300. For an hour and a half flight, I don't know how much of a difference it makes (except for the additional baggage).
