Flight delays occur when an airplane is unable to take off or land at the scheduled time. This can happen for various reasons, such as bad weather, technical issues with the aircraft, or air traffic congestion. When a flight is delayed, passengers may have to wait at the airport, which can be frustrating and inconvenient. Airlines often provide updates about flight delays through announcements or mobile apps. Passengers can check the status of their flight and may receive compensation or rebooking options if the delay is significant. Understanding the reasons behind flight delays can help travelers manage their expectations and plan accordingly.
