How to check whether the plane is stopped, and if so, will you notify the individual?

Generally, you leave your phone number when you buy a ticket. If the flight is changed, cancelled or delayed, the airline will inform you through the ticket office. If you leave your mobile phone number when booking online, the airline will also send you a text message. If you don't receive such notice three hours before departure, the flight will usually take off on time.

Of course, if you are still worried, you'd better call the departing airport, find the service hotline of the airport, and make a phone call before leaving for the airport.
