Thanks for reading. I've added a section about this in the "logistics and risks" section.

I'm basically adding this to the list of hard problems to be solved, instead of providing a specific solution. I do not know if the existing airports can be remodeled or operated differently in order to handle more passengers. I do not know if a high-speed rail will be put in place that could quickly shuttle people to an airport in Bakersfield, etc.
