Your air tickets are likely to make up a large portion of your total safari cost. Our specialty is arranging and running safaris - we generally leave the air ticketing to specialists.
Airlines sell only a limited number of seats at the lowest fares.
When those seats sell out, the price goes up. Purchase all of your tickets, both international and regional at the same time from the same source. It's almost always less expensive to use only one airline or code-sharing airlines for a trip instead of two. Make a reservation as soon as you know your travel dates to increase your chances of finding a good fare. Very importantly, avoid making changes once your tickets are purchased.
