Lol business people won't care if the costs go up. They already pay extra to be able to sleep on their Intercontinental flights to go drinking "for business".

It'll be you and I who won't be able to go on vacation anywhere that requires crossing a major body of water.

There might be better transportation, but it is more costly. Just take germany for example, it is usually a lot more expensive to travel using long-distance trains than it is to travel by airplane. And not forgetting all the stress you get by travelling with the Deutsche Bahn cos their trains are literally only 60% of the time on time. And that's not including cancelled trains, lol.

Don't the shipping and cruise industries also get constant flak for their emissions?

Exactly and there's more of us than there are billionaires, so our emissions need to be cut while they can keep on doing whatever the fuck they want. And THAT is never going to sit well with most people.

If you price people out of short haul flights, that just means they're even less likely to be able to afford long flights which cost money even in good times.
