Best Airline Deals?

[annie]

Hi.  We, a family of 2 adults, 5 children, are booked to fly to South Africa June 2008.  We then need to get to Entebbe, Uganda, where we will spend about a week.  Our aim is to then go overland to Nairobi, via Safari. Any ideas who would provide the cheapest airfares within Africa?  Are they a reliable airline?  Thanks.
