Don’t be so sure, both Kulula and 1Time have had horrendous delays in the past, some teething problems are to be expected.
Yes, but they didn't start with one aircraft, and Kulula had the backing of British Airways to carry their pax if they went tech.
All the SA carriers suffer from the same failing, highly variable service delivery levels, and it's determined by who you get to deal with on board or on the ground, and how or if they've been trained. In the past when there was only one carrier, it was always the same, poor, but competition has led to a generally higher standard but with frequent major failures.
I'd also like to see Velvet Sky succeed, but I don't see it happening.
