It is well know that the roads in Kenya are not the best in the world-particularly if you get off the well traveled road.(It'll take HOURS to Drive from Nairobi to Masai Mara), so...
Many of the of the well known Safari Parks have landing strips-
Masai Mara, Nanyuki, Samburu, Meru, Lewa, Amboseli,
as well landing strips along the coast and at some of the popular beaches- Diani, Mombasa, Malindi and
Lamu (via Malindi).
They also have scheduled direct flights from one National Park to another- for example you can fly from Samburu National Park to Masai Mara without going through Nairobi. That way there is no need for you to charter the more expensive charter flights. Their fares and schedules are available on their website.

These planes are built for short take-offs and short landing strips like the ones you find at game parks and beaches
