A flight delay occurs when an aircraft is unable to depart or arrive at its scheduled time. Delays can happen for various reasons, including bad weather, technical issues with the aircraft, or air traffic control restrictions. Passengers are often informed of delays through announcements at the airport or notifications from their airline. Airlines typically strive to minimize delays, as they can lead to passenger dissatisfaction and logistical challenges. In some cases, passengers may be entitled to compensation if their flight is significantly delayed. Understanding the reasons behind flight delays can help travelers manage their expectations and plan accordingly.
