Hello- We are doing this trip in July 2026. A very recent Tauck trip to Australia/NZ made me a believer in trying to find direct flights with no connections (outside the USA). I found a United direct flight (Dreamliner) from EWR to JNB (flying AirLink to VFA) and a return flight from CPT to IAD. I also wanted to comment that I use the travel agency Pavlus. If you allow them to book both your Tauck trip and your flights they give you a rebate. On that recent Aus/NZ trip our rebate was nearly $3k.
