What should the airline do if the plane is late?

? There are many reasons for flight delay, such as departure weather, route weather, landing weather and alternate weather. Any one of the influencing factors may cause the plane to fail to take off. After all, once in the sky, it is not as convenient as on the ground. I am a railway operator and have dealt with railway traffic controllers. When the weather is bad, the railway traffic will follow the principle of "stopping by mistake is better than doing well". I think the aircraft dispatching command should be similar to this, or even stricter.

? After all, it is in the sky, and the railway is at least on the ground. There is also air traffic control, which is also the reason for the delay. Perhaps most people are thinking that the sky is so vast that they can fly at will. But in the sky, planes, like cars and trains on the ground, have fixed routes and flying heights. In the sky, unlike on the ground, they can stop if they want. Therefore, the possibility of meeting other flights on the flight route should be considered, and the flight route and flight altitude should be arranged reasonably. In addition, China's aviation sector is controlled by the military. If the flight area approaches or passes through the military control zone, it is necessary to rearrange the flight route.
