Worst airline and unreliable

Try this airline at your own risk. Flight from Johannesburg to Durban delayed. Why did they allow passengers to board the plane is beyond any understanding. We sat for over 3 hours and little communication from the cabin crew. Appointments missed. So much for technical issues in the morning. Unreliable and the worst is no refund for your ticket unless a flight exceeds 5 hour delay. This is for an hour flight. **** ticketing rules as well
