Major airlines fly from Europe, Australia and the US to Windhoek; however, flights are limited and it's often cheaper to fly into South Africa and go overland or by plane into Namibia from there. South African Airways and Air Namibia operate daily flights between Johannesburg (Jo'burg), Cape Town and Hosea Kutako International Airport, 42km (26mi) east of Windhoek. Air Namibia also flies twice weekly between Windhoek and Harare, Victoria Falls, Lusaka, Maun and Gaborone. Charter-flight operators are numerous, although their services are expensive. Namibia has an excellent system of tarred roads covering the country. Car hire is available in Windoek and at the airport.
