What may a flight attendant advise a passenger with a disability to do while waiting for assistance?

A flight attendant may advise a passenger with a disability to remain on board while waiting for assistance for several important reasons. Keeping the passenger on board ensures their safety and comfort, as the aircraft environment is controlled and monitored. It minimizes the risk of the passenger navigating potentially crowded or confusing airport areas alone, which could lead to accidents or further difficulties in movement. Additionally, remaining on board allows the flight crew to maintain awareness of the passenger's needs, ensuring that assistance can be rendered as soon as possible without any complications.

This procedure is particularly vital because it aligns with ADA (Americans with Disabilities Act) guidelines and ensures that the passenger is not left unattended in a situation that could be stressful or unsafe. Other options, like taking a walk or proceeding to the exit, could put the passenger at risk of injury or discomfort, or result in delays in receiving the necessary help.
