There are two international airports in Kenya. Jomo Kenyatta International Airport in Nairobi is within about 30 minutes drive from the city center. In Mombasa you will find the Moi International Airport. International airports in Kenya have basic facilities available to the traveler 24hrs. Some of these include a bank and foreign exchange facilities, car hire service desks, information desks, duty free shops and restaurants.
Most people prefer to fly to Kenya as opposed to going by sea for the obvious reason of time.
These are an excellent choice for someone who does not want to travel alone because of lack of familiarity to the country. Internal flights are also scheduled from these two airports however Wilson Airport located in Nairobi West area, just before the Carnivore restaurant, handles the bulk of charter flights.
