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.
Fly on workdays: As many passengers prefer to fly on week-ends, week-end tickets sell first. If you don't book your trip well in advance (2-3 months beforehand) you may notice, for example, that Thursday flights are cheaper than Sunday flights. Some low cost carriers have special promotions on the flights during the week.
