Code * * * flights, how do airlines make money?

The main advantage of flying * * * is to expand the route coverage, so that more people can choose their own airlines to travel and make a profit. It is very expensive for a foreign airline to arrange routes in other countries. For example, most foreign airlines can only fly north to Guangzhou, and then there are no flights to second-and third-tier cities, or conversely, China's planes can only fly to foreign capitals (London, Paris, Rome) or major cities (Munich, San Francisco), and then there are no flights to second-tier cities.

For domestic airlines, they often have a perfect coverage network of major cities-central cities-secondary cities-remote cities. Air China, China Eastern Airlines and China Southern Airlines are in China, Air France is in France, Lufthansa is in Germany and Austria, and United Airlines is also in the United States.

In general, the tourists of international flights are often not major cities. For example, travelers who go abroad from Shanghai may come from all over the country. They first reached the main city through the domestic transportation network, and then went abroad. Most of the destinations of people who go abroad are not foreign capitals or central cities, but other small cities, which need to be contacted.

Therefore, through the code * * *, passengers can make a one-stop transit from a second-tier city in their own country to a second-tier city in another country only by purchasing a ticket of their own airline, without purchasing a ticket in reverse. More convenient travel arrangements will inevitably make customers choose your company to travel and increase passenger flow.
