I think passenger ships are going to make a comeback at some point in the next 50y. International air travel is one of the few big climate impact vectors with no reasonable substitute. Domestic you have possibility of better all-electric high-speed rail...

Cruise ships 20 something mph. Airships maxed out in the 40s at about 4x that. Possibly faster now. Fast shipping is one of the primary CO2 generating industries though, right?

In total yeah, but in per mile/per pound basis air travel is way worse. There’s just a lot less mass moving that way.
