Why are plane flights always late?

Most of the reasons are due to the weather, such as heavy snow, the snow on the runway is too deep to be cleared in time, which leads to the plane not taking off normally, or the safety of the plane cannot be guaranteed after taking off, so we can only wait for the weather to be better.

This is the most common thing in winter, and there is nothing we can do. Although the airport can know the weather in advance through the weather forecast, it is not 100% accurate in this case, so we can only say that we should wait patiently.

There is also the reason for the plane. For example, if there is something wrong with the plane on the day of the flight, it is necessary to find out the reason and solve it before taking off, otherwise it will not be a joke on the passengers' lives. This will take a little time.

If the problem is not serious, solve it in time, and you can still take off a little later. If it can't be solved at the moment, passengers may change to another plane to let them take off, or they can't fly directly. Passengers can refund tickets or change other flights for free.

Moreover, there are personal reasons, which are often seen in the news. For example, the last time I saw a report, a female passenger thought it was fun and opened the security door, which made the whole plane unable to take off normally, so she stopped there and took off an hour or two later.

Or passengers have disputes on the plane that affect the normal take-off, and the service personnel on the plane can't solve it, so they can only ask the airport police to come up and solve it. Even if someone on the plane gets sick during take-off and needs to be sent to the hospital for compulsory treatment, it will also lead to the delay of the plane.
