It’s a great question, but unfortunately, I’m not aware of any publicly available research. I always heard of the same actuarial data that
@Derg has mentioned here before about pension records from DALPA showing early deaths, but I’ve never been able to get my hands on the data. If recollection serves, though,
@Derg said he had either seen the data or was supremely confident that the source was accurate.
There are several problems with the study you linked, though. First, it only looks at American Airlines pilots, not a diverse dataset. Second, it’s a study that is now 26 years old, and basically shows data from the “golden age“ of pilot contracts when everybody at American (save reserves) got tons of time off, had astronomical benefits and a fully funded pension, and made bank so they didn’t feel the need to live on voluntary overtime. And finally, they specifically excluded anyone from the study who retired early. That’s a big problem since someone with medical issues is going to retire early. You’ve basically screened out a big chunk of people who would have weighed down the average.
That’s not to say the study isn’t accurate, though. It may well be. We just don’t have the publicly available data to know, and it does contradict what credible sources have said other data shows.
