Huge disappointment for Korongo Airlines! Poor service, poor communication! Bought a ticket from Johannesburg to Lubumbashi. Flight delayed 3 times, without giving customers any reason!! No compensation, no hotel, not even a discount. I do not live in Africa, but I do business here, therefore I lost a lot of money! Not flying with this airline anymore.
Consider secondary airports: Secondary airports (smaller airports or airports that are further away from the city center) usually have lower airport taxes, which translate into lower ticket prices. When comparing the prices of flights that depart from 2 different airports you need to also take into account the price you pay for transportation to and from the airport (shuttle bus, train ticket, gas, etc).
