'IOSA a ticking box excercise' - don't be daft.
The airline I worked for spent a huge amount of money and time to become IOSA accredited.
Air Zim were a fantastic airline to fly on, and by all accounts for, before the whole country went to the dogs. If they are indeed IOSA certified then it is because they met and complied with some of the most stringent safety regs currently in place. IOSA can pull this certification if they deem it is necessary and one would think that they are watching closely.
