It is a truly small country, with a population of less than 40,000 and an area of barely 2 km2. Its borders total only 6 km, with a length of only three kilometres. In other words, there is no space for an airport, not even a small one, unless the population were to decrease drastically to half of what it is now in order to allow the construction of a very limited airport. Where it would anyway be very complicated to land.
Monaco has solved the problem of not having an airport by signing an agreement with the neighbouring city of Nice, 30 minutes away by car and slightly more than five by helicopter. Yes, an aerial connection between Nice and the Principality of Monaco, although it doesn’t exactly come cheap. So most flights finish off with a car or bus trip to reach this small country.
