I found a flight with Botswana Airways on Kayak.com from Johannesburg to Kasane that is listed at 273 USD per person. When I go to the Botswana Airways website to book my tickets, the price goes up to 340 USD per person. Why is there such a big price difference? For the two of us, it means paying 130 more bucks?! I can't even book at the low price on Kayak.com since they redirect me to the Botswana Airways website. Ugh!
