I've sometimes thought I'd prefer to travel by sea, especially for short to medium length trips between countries where ferries are not an option.<p>Has air travel totally replaced such a travel option? Why?<p>Not everyone is in so much of a hurry that a week or so of travel by sea is not an option, and that could reduce emissions. Or is it that the economics do not work out?
> Has air travel totally replaced such a travel option?<p>Given that there appear to be no "sea route" travel options for passengers remaining, the answer would appear to be: yes.<p>> Why?<p>Most likely, speed. Second most likely: cost.<p>> Not everyone is in so much of a hurry that a week or so of travel by sea is not an option, and that could reduce emissions.<p>But, also, not enough people are willing to take a week of sea travel to get from point A to point B to provide enough volume for the ships. People spent a week at sea in 1900 not because they wanted to spend a week at sea but because there was no other faster option for that travel.
> Not everyone is in so much of a hurry that a week or so of travel by sea is not an option, and that could reduce emissions. Or is it that the economics do not work out?<p>Speaking as an American, most people here don't have the luxury of taking a week off for a leisurely cruise to a destination.<p>I'm also not sure just how much a ship sailing across the ocean or a sea compares to an airplane traveling the same distance. I wouldn't be surprised if they were comparable.
