It was not my intent to exclude regionals operating regularly-scheduled white-label service for the majors.

It was my intent to exclude microscopic commercial operators doing charter flights, tourism, and other similar activities.

I sincerely apologize for the omission, I did not recognize that that Comair flight was operating under the United banner.

Then you also have to count https://en.wikipedia.org/wiki/Chalk%27s_Ocean_Airways_Flight... and it's 20 fatalities. That was a regularly scheduled flight by a US carrier.

Chalk’s Ocean was not a major airline and it was not a regional airline performing white-label service for a major airline.

I hope you can recognize that a company privately operating a fleet of seven floatplanes is not particularly relevant to a discussion about the safety of mass passenger air travel, in much the same way that a carnival operating a rollercoaster is not meaningful when discussing passenger rail.

Why isn't it relevant? They obeyed the exact same rules and regulations (FAR Part 121). That's the exact same part of theregs that applies to Delta and United. They weren't a charter or sightseeing operator.

They were, prior to the their closure, the oldest operating airline in the US and something like #3 worldwide, post-dating only KLM and one of the other European flag carriers. (Lufthansa, maybe? I don't have the list handy)

I'm pretty sure the US majors aren't flying airframes that haven't rolled off a production line in half a century, from manufacturers that shuttered their doors over a decade prior.

I'm also pretty sure that you, nor anyone you know, nor anyone they know has ever flown on Chalk's.

Then you're pretty surely wrong. I visited the Bahamas a number of times as a kid.

Your whole approach here feels rather bad faith/no true Scotsman-y. Of course you’ll have no fatal crashes if you say every fatal crash doesn’t count for some reason or another as not a real crash.
