Why is the flight delayed one day in advance?

The flight was delayed one day in advance for the following reasons:

1. Weather reasons, such as bad weather and fog, will seriously affect the normal take-off and landing of flights, resulting in flight delays or cancellations.

2. Traffic control, in this case, the explanation of civil aviation is even less, because it is considered that it is not its own reason and it is impossible to change this situation. You can only wait for the notice honestly, and it is useless for passengers to worry.

3. Passengers' reasons, such as passengers' failure to board the plane or temporary cancellation of the trip, may also lead to flight delays.

4. Aircraft deployment, all subsequent flights delayed due to other specific circumstances are counted as late by civil aviation, and all reasons for delay by civil aviation are called aircraft deployment.

5. The flight cuts in line, and some delays are caused by the plane "cutting in line".

In short, there may be many reasons for the flight delay one day in advance. I suggest you be patient and understanding when booking and flying.
