We are concerned about air too. Using our Delta miles for Business class. One of us will get a free ticket 120,000 miles and the other will have to pay for M class coach and upgrade with 50,000 miles to Business. Quoted about $3500 for the M class coach to Joburg for one. Hope we can pull it off. We are coming all the way from the West Coast, so add on 5 more hours than you New Yorkers. We are a little flexible on our days of travel though. See what happens in a week or two. I wish Delta would commit to the Cape Town flights and start booking. I called and they said IF and WHEN (they have no idea). Heard from others that they will start flights June 3rd. Let's all keep looking for deals!
