While I agree, one would expect incidents to scale roughly with the rate of fatalities. With PIA having 2 orders of magnitude more fatalities in this century, it would take some pretty extraordinary non-fatality incident statistics to declare that PIA is much safer than Southwest. Also worth considering is fatalities per flight hour. While I couldn’t find accurate flight hours for all the airlines, Southwest has a much larger fleet (752 vs. 31). Combined with a much lower fatality count (arguably 2 vs. 102), this implies that Southwest is much, much safer than PIA. It’s possible that non-fatal incidents can cover that gap, but at a high level analysis this seems implausible.
