A boarding gate is a designated area in an airport where passengers wait to board their flights. It is usually marked with a sign displaying the flight number and destination, helping travelers know where to go. At the gate, airline staff check boarding passes and ensure that passengers are ready to board the aircraft. Once the boarding process begins, passengers line up according to their assigned groups or rows. This organized approach helps ensure a smooth transition onto the airplane. After everyone is on board, the flight attendants prepare for takeoff, making sure all safety protocols are followed.
