There’s a departure tax of ZMW156 per person applicable to all international flights. Before you make your way to the relevant counter to pay, check with your airline, as it’s often included in the price of your ticket. You will have to pay the ZMW58 tax at the counter (just outside and to the right of the entrance to the domestic lounge) for all domestic departures.
The humble international airport has slim pickings as far as services are concerned. There's a coffee stand in the main hall, or if you have time on your hands, make your way upstairs to the Copper Chimney Restaurant or the Nsonga Walala Cocktail Lounge. Once through security for international flights the only eating option is a very basic bar selling reheated burgers, hot dogs and pies (ZMW25); a couple of shops sell a poor selection of over-priced curios. Several ATMs, a bureau de change, Europcar and Avis rental car offices and Airtel and MTN mobile-phone company offices are in the hallway immediately outside the arrivals area.
Queues for immigration at Lusaka’s international airport can be long whatever your arrival time; however, they can be exceptionally long and frustratingly slow late at night and early in the morning when few officers are on hand. With that in mind, it’s best to use the bathroom before disembarking from the plane, do your best to get as close to the front of the line as possible and join the much shorter queues earmarked for Zambian residents and SADC card holders or the one for diplomats. Be polite when feigning ignorance and you’ll likely have no problems. Insure that you have US$50 in cash for the entry visa – change is sometimes not available. Somewhat incongruously, a fingerprint scanner is used to identify visitors.
