If you want to "reason" that way, take into account that (1) if people started dying from air travel at high rates, they'd do less of it; and (2) societies with much higher death rates have no problem growing anyway, as they compensate with higher birth rates.

That doesn't seem to stop people from driving cars.

That's just survivorship bias. Why would one cause the other? There were also societies with high death rates and low birth rates which for the obvious reason no longer exist.

If you claim to be worried about extinction of the human race, you'll have to consider all societies, not just the ones with pathologically low birth rates. A tiny group of people committing suicide has zero effect on the overall human population.
