Are flights from Guangzhou to Nanchang often delayed? Flight MU5256, the flight after 4 p.m.

Hello, this passenger, flight MU5256 of China Eastern Airlines, took off from Guangzhou Baiyun International Airport at 16:35, and arrived at Nanchang Changbei Airport at 17:55, with a flight time of 1 20 minutes and a flight distance of 665KM. The delay rate is not very high. There are many reasons for the initial delay. For example: weather, runway, aircraft flow, yard control, mechanical failure, temporary reasons, etc. Generally speaking, it should be the flow control caused by the weather problem in Guangzhou. Recently, there are frequent thunderstorms in Guangzhou, and planes will pass through the clouds when they rise. In order to avoid Lei Yun, the aircraft will turn on the weather radar, but if there are too many thunderclouds, some can't escape, thus reducing the safety factor of the aircraft. For the safety of passengers and to prevent the plane from being struck by lightning, the tower will guide the plane to flow control, so it will cause a short delay, so I think it depends on luck. Not only has your flight been delayed recently, but Beijing-Guangzhou 747 and 777 have also been delayed many times, sometimes as long as three hours. Please be patient. I hope my answer can help you and I hope you will adopt it. Thank you.
