Why are there no flights after 12 in the afternoon?

This is because people may be in a relatively tired state at this time and are not suitable for flying, and the visibility at night is very low and the weather at night is unpredictable, so this time is not suitable for flying. When we buy air tickets, we will find that the evening air tickets will be cheaper than the daytime air tickets, but there will be basically no flights at night 12.

Twelve o'clock at night is when people are very tired. At this time, it is more difficult for people to stay in a state suitable for flying because of their biological clocks. If the captain wants to fly the plane normally, he not only needs to master all the relevant equipment of the plane, but also needs to be awake. Once the captain makes any mistake, it may bring life danger to the whole crew, so no captain will fly after twelve o'clock.

In addition, in the middle of the night, visibility is very low. When flying during the day, most people can see the situation around the plane very clearly, always grasp the flight environment of the plane, and let the captain make a more accurate judgment. Moreover, the ground crew can also cooperate with the captain to adjust the plane to a suitable position. But in the middle of the night, the visibility is not so high. At this time, flying may cause problems because it does not grasp the surrounding environment in time. Moreover, the weather is unpredictable in the middle of the night, and it is difficult to grasp the wind speed and airflow. It's not suitable for flying at this time.

So, there are no flights after midnight most of the time. There may be one or two flights unless it is during the Spring Festival peak or special festivals.
