I think there are a few other factors to take into account, such as private jets flying faster on average, no layovers, etc. Looking only at flight hours doesn't really show the risk for an individual (e.g. an exec choosing between commercial flights and private flights). My guess is that the average exec is about as likely to die from one vs the other since the exec would spend more time flying in the commercial jet. So it's really not a fair comparison and I wouldn't be surprised if they're functionally equivalent after taking into account all major variables.
