The plane can't take off at night for some reason, but it will take off the next morning. How about hotel accommodation at night?

Hello! It depends on the reason. If the flight is delayed or cancelled due to maintenance, flight deployment, business, crew and other reasons, airlines will provide passengers with flight dynamic information, arrange meals or accommodation and other services.

If the flight is delayed or cancelled due to weather, emergencies, air traffic control, security check and non-carrier reasons such as passengers, the airport can provide passengers with flight dynamic information and assist them in arranging meals and accommodation, and the expenses shall be borne by the passengers themselves.
