Flights to Nairobi are often cheaper than to Kilimanjaro Airport. Is that worth the extra transfer, or should I fly straight in?
How do I get to Kilimanjaro: fly to Kilimanjaro Airport or to Nairobi?
Fly to Kilimanjaro International Airport, JRO, if you can. It sits between Moshi and Arusha, an hour from either town, and is served by KLM from Amsterdam, Qatar Airways, Turkish Airlines, Ethiopian Airlines, Kenya Airways and others. See also Getting there and around.
