The flight has landed at the alternate airport due to the weather. Can passengers get off the plane?

Due to the weather, the flight has landed at the alternate airport, and passengers are not allowed to get off the plane.

Generally, alternating weather is mostly due to thunderstorms, which come and go quickly. So the crew stopped, refueled, and left immediately, which was very troublesome.

If there is heavy fog, it usually takes a long time, several hours or even a whole day, so the crew will let passengers off the plane.
