標題：Extra Flight: The Challenges and Benefits

When an airline operates extra flights, it can be a challenging task, but it also brings many benefits to customers and the airline itself. Firstly, extra flights can help alleviate delays and congestion caused by unexpected events such as weather or technical issues. This can ensure smoother operations and better customer satisfaction. Secondly, extra flights can provide customers with more options for travel, especially during peak seasons or when there is a sudden surge in demand.
