The flight of Changsha Airport was delayed due to the weather, and the pre-flight has been prepared to drop to other airports. In this case, do you have to wait until the pre-flight arrives?

in general, it is necessary to wait. If it's a big airline, it may transfer your plane to pay for the flight. If it's a small airline like Chunqiu, it's out of the question. But you're on standby because of the weather. Even if you are transferred to a plane, you can't get in or fly. So in a word, you have to wait.
