As someone who used to love flying and relied on it for income, family, etc, but stopped as I learned how much it polluted, pleasantly surprised to find how much my life improved without it, I read articles on the cruise industry as applying to flying. Ticket costs don't cover the costs of cleaning their environmental damage. Few people could afford it if they had to pay for that damage.

In the case of contributing to pandemics, flying spreads viruses incredibly effectively. Boats trap a few thousand people at a time. Flights bring the virus to population centers of tens of millions in hours.

For the time being, people associate flying with seeing loved ones and making money, so they associate not flying with never seeing their moms or losing their jobs. Experience shows the opposite. The more people fly, the more dispersed their families, so the less they see loved ones. Flying forces companies to fly people everywhere.

I predict the vitriol people are starting to show for cruises will eventually make it to flying, however hard to conceive today.
