Has anyone got any experience of flying London to Nairobi via Zurich with Swiss air. These are the cheapest flights I can find for end of July 2012. £498 return which seems good value to me. Hope someone can help. There are 4 of us 2 adults + 16yr +13yr old so all have to pay adult prices. I am hoping to book a safari before we go so what I can save on flights will go on our safari. Any suggestions regarding flights please.
