Regarding "A Romantic's Safari" (Oct. 5) on Botswana, I noticed an omission from your list of ways to travel to Johannesburg, South Africa. I just returned from a trip there via American Airlines. They go through Miami (where you change planes) to Cape Town (stop, but no change of planes) and on to Johannesburg; and through New York (only one change of planes in New York) to Johannesburg. It's a code-share with South African Airways. Great service. Right on time. Much better than going through London as you suggested, I think.
Also, I highly recommend Wild African Ventures in Pasadena for booking trips to the area. They work through Safariplan in Johannesburg.
