There will be an exception to the every airport needing aircraft. Kaldus Air will accept incoming planes from friendly countries, but unless there was a big demand – there will be no need to spend hundreds of millions on a airplane that might not get the workout to make it worth the purchases. Keep in mind, the airplane will only be able to serve 1 flight at a time. If 2 flights were needed, then that would be even more expensive. Again, Kaldus will be a new country, and it might simply not make sense to have long haul aircraft.
With that in mind, it would be assumed that Kaldus is friendly with their neighbors. There will be efforts to have high-speed rail to connection cities neighboring the friendly neighbors. The high speed rail will be able to take a passenger to Kaldus International Airport. While this might not make sense since there are no long haul flights from Kaldus Air, there will be short haul airplanes that would connect to regional airports and therefore eventually connect to individual counties.
There will be a couple of exceptions to this rule. There will be an Airbus A400M cargo aircraft that would transport a sedan, and 2 SUVs ahead of any international trip that I might have to endeavor. The choice for Airbus is simplicity of the platform. This role of the aircraft is to assure that I would have everything I need for when I arrive in a country. There will also be an Airbus A350-1000 that would be the royal aircraft to take me to another country. The cargo plane will leave ahead of me to be ready for when I will arrive.
