What is the real reason for the plane delay?

Reasons for long delay: 1. There is a mechanical failure in your flight (of course, ordinary passengers can't know the cause of the failure).

2. Due to the above or the following factors, your flight did not take off on time at the departure airport of the last flight. Because there are not enough planes owned by domestic airlines, the utilization rate of planes is high, and there is no emergency standby plane, once the plane at one end of the round-trip route is delayed, the plane at the other end will delay the departure time, causing the plane delay.

Weather reason: 3. The bad weather conditions at the departure airport did not meet the departure conditions, resulting in delays.

4. The bad weather conditions at the airport did not meet the landing conditions, resulting in delays.

5. The weather conditions over the flight route are not good, which does not meet the flight safety conditions, resulting in delays.

Reason for departure from airport: 6. The departure airport is too nervous on the landing runway (some small and medium-sized airports in China often have only one landing runway), which leads to the delay of the plane.

7. The departure airport channel is tight, and the plane can't take off and land in time, which leads to the delay of the plane.

8. Ground handling services at the departure airport (including fault inspection before departure, ground handling services such as refueling, water filling and food distribution after landing, and trailers and boarding ladders in place, etc.). ) is inefficient or wrong, resulting in delay.

9. The baggage consignment service at the departure airport is inefficient or delayed due to mistakes.

10. The air traffic control service at the departure airport is inefficient or delayed due to mistakes.

Reason for arriving at the airport: 1 1. Arriving at the airport is delayed due to the tight runway (some small and medium-sized airports in China often have only one runway for taking off and landing).

12. Due to the tight arrival channel at the airport, it is impossible to arrange the take-off and landing of the aircraft in time, resulting in the delay of the aircraft.

13. Ground services at the airport (including fault inspection before take-off, ground services such as refueling, water filling and food distribution after landing, as well as trailers and boarding ladders in place, etc. ) inefficiency or error, resulting in delay.

14. The baggage check-in service at the airport is inefficient or delayed due to errors.

15. The air traffic control service arriving at the airport was delayed due to inefficiency or error.

Air reason: 16. Because the flight of aircraft strictly follows the flight trajectory, all aircraft must follow a specific flight trajectory. In order to prevent traffic jams or even rear-end collisions between aircraft and other aircraft in the same channel during flight. On the grounds of flow control, airlines will delay the take-off time of aircraft or reduce the flight speed of aircraft in the air, or even temporarily change the flight altitude or flight path of aircraft. These factors will cause the plane to be late, and of course the plane will arrive early. Nothing more than being driven out by the plane behind, and driving faster.

17. During the flight, the flight speed can't reach the set speed for various reasons, resulting in the delay of the aircraft.

Some special reasons: 18. Some airports are both military and civilian airports, and both military and civil aviation use the same airport. It seems that there is an unwritten rule in our country, that is, when there is a conflict between military aircraft and civil aviation flights, military aircraft takes precedence, and when there is a conflict between military aircraft and civil aviation flights on the route, military aircraft takes precedence. This has caused a lot of so-called air traffic control.

19. When the plane flies over the capital Beijing or Nanjing, Guangzhou, Jinan and other large and medium-sized cities which are also important military areas, it is very likely to encounter air traffic control in order to avoid conflicts with military aircraft or leaders' special planes.

20。 When there are important passengers on your plane (government cadres at or above the provincial level, military and political leaders in the army or other important or special passengers), the plane will give priority to or delay the takeoff of the plane on the grounds of air traffic control. Of course, it depends on whether the leaders are in place on time. If the leaders are in place on time, the plane can take off on time. If the leader is late, the plane and passengers must silently wait for the leader's condescension and patronage.

The above 20 articles do not contain other force majeure factors except weather factors. Aircraft delay is not good for airlines. They are responsible for passengers' meals and accommodation, airport use fees and rental fees. Simply put, airlines spend money every minute after the plane is delayed. However, due to the above 20 reasons and our unique national conditions, it is normal to be late.
