"Flight Departure" refers to the scheduled time when an aircraft leaves the airport to begin its journey. Passengers must arrive at the airport well in advance to check in, go through security, and board the plane. Each flight has a designated departure gate where travelers gather before boarding. Airlines provide information about flight departures on screens throughout the airport, showing details like flight numbers, destinations, and boarding times. Delays can occur due to various reasons, including weather conditions or technical issues. Travelers should stay informed about their flight status to ensure a smooth departure process.
