Flight cancellations occur when an airline decides to not operate a scheduled flight. This can happen for various reasons, including bad weather, technical issues with the aircraft, or staffing shortages. When a flight is canceled, passengers are typically notified in advance and may be offered alternative travel options or refunds. Airlines often strive to minimize cancellations, as they can lead to customer dissatisfaction and financial losses. Passengers are encouraged to check their flight status regularly and consider travel insurance to protect against unexpected changes. Understanding the reasons behind cancellations can help travelers better prepare for their journeys.
