If the passenger does not show up in the regular time at the Gate, he is withdrawn from the cruise. If he travels with checked baggage, his baggage is also withdrawn from the cruise. Airplanes must depart on time, unless there are emergencies, such as a technical fault or late arrival of the plane from the previous flight. If a passenger is traveling with a transfer and his first flight is delayed, in most cases the second plane will not wait for him. It is the carrier's decision, however, it is recommended to report to the Gate for the second flight. After arrival at the transfer airport, check the status of your second flight on the airport screens ;)
