The main domestic airports are at Lusaka, Livingstone, Ndola, Kitwe, Mfuwe, Kasama and Kalabo. Dozens of minor airstrips, most notably those in the Lower Zambezi National Park (Proflight flies here regularly), Kafue National Park and North Luangwa National Park, cater for chartered planes.
The departure tax for domestic flights is US$8. Proflight tickets include this tax in the price, but for other flights it must be paid at the airport.
Proflight is the only domestic airline offering regularly scheduled flights connecting Lusaka to Livingstone (for Victoria Falls), Lower Zambezi (Jeki and Royal airstrips), Mfuwe (for South Luangwa National Park), Ndola, Kasama and Solwezi. From 2017 they will commence a flight to Kalabo for Liuwa Plain National Park.
Baggage for all flights is 15kg; otherwise you can upgrade your fare to get 23kg or 32kg. Carry-on baggage on all flights is limited to 5kg.
There are plenty of charter-flight companies (Proflight also does charters) catering primarily for guests staying at upmarket lodges/camps in national parks. Flights only leave with a minimum number of prebooked passengers and fares are always high, but it’s sometimes worth looking around for a last-minute, stand-by flight.
