Never on Time

I’m a regular flier commuting between East London and Johannesburg. Always kulula flights are delayed. Flight MN806 due to leave at 18:05 delayed and scheduled to leave at 17:15. No explanation. A flight from Johannesburg delayed for over 3 hours. I know the argument is safety first. But can one of the flights that I catch with kulula be on time.... please make this a measurable KPI.......
