Immediately after the war of 1914-1918 in Western Europe, and then in other countries, a number of aerolines were installed, that is, air lines connecting various cities not only within countries, but also between different countries. Thus, national and international aerolines arose. Airplanes and airships running on them fly according to a certain schedule and tariff, carry hundreds of thousands of passengers, millions of letters and various cargoes.
