Final answer:
After a flight cancels, the original gate information may no longer be displayed, as the gate may be reassigned or remain empty. Passengers should stay updated by checking with the airline's customer service.
Step-by-step explanation:
When a flight cancels, information about the cancellation will be made available to passengers in the airport, often on the same display where the original gate information was listed. However, the original gate number may no longer be displayed after the cancellation is announced. This is because the gate space may either be reassigned to another flight or remain empty until the next scheduled departure. The airline and airport staff ensure that passengers receive updated information regarding cancellations and any potential rescheduling or accommodation arrangements. It's crucial for travelers to stay informed and check with the airline's customer service for the latest updates.
