How different would U.S airports be in a universe where the USA built high-speed rail instead of the freeways?
In my alternate history universe, the following changes occurred.
- The USA won the war of 1812 and the territory of the USA circa 2026, encompasses all of what would be Canada, Greenland, Iceland and the Baja California Peninsula.
- Humanity's technological and scientific progress between 1942 and onwards is moderately accelerated.
With those two details in mind: In my timeline, the USA never built the Interstate Highway System, instead it kept using and maintaining the pre-1956 highway system which is longer in my timeline on account of the USA being much larger.
Instead of building the Interstate Highway System, the USA of my timeline built a high-speed rail system between 1956 and 1976 which would ultimately connect all the major cities with Maglev trains. By 2026, the Interstate Maglev Network allows citizens to cross the entire country in less than a day's time.
Anyway...
I'm wondering what airports and air-travel would be like in my alternate timeline?
From my perspective, I think there would be fewer airports and airlines because the IMN eliminates or reduces the need for air-travel between the states. Airports would only exist in major cities that receive a lot of international visitors and cargo and air travel would be primarily limited to overseas destinations. As a result, I think air travel would be more of a luxury for upper middle class persons and above.
What do you think?
