Worst airline in SA

I always fly SAA or Kulula because they're always on time and their service is good, but tried Mango recently because of their prices. Worst decision ever! My wife's flight was 1 hour 30 minutes delayed! I mean how can you be 1.5 hours delayed on a domestic route? Furthermore, they didnt offer to chnage the flight to an early flight. Needless to say, I will never fly Mango again! Stick to Kulula and SAA
