Which term describes a customer unable to board or move about the plane unaided?

• A. A customer who can move about the plane unaided.
• B. A customer who is unable to board or move about the plane unaided.
• C. A passenger with a wheelchair available.
• D. A passenger who refuses to board.

Answer: (B)

Understanding who needs help with mobility is essential for safe and smooth cabin operations. The description points to a passenger who cannot board or move about the plane unaided, meaning they require assistance from crew or ground staff. This is the standard way airline teams categorize travelers who need support—whether it's wheelchair assistance, help navigating the aisles, or extra time and space to get settled safely. Recognizing this need triggers the established processes for providing appropriate help, coordinating with ground services, and ensuring the passenger can board, be seated, and move around the cabin safely.

As for the other scenarios: one describes someone who can move on their own, which means no assistance is required; another mentions a wheelchair being available, but that doesn’t by itself indicate an inability to move unaided; and the last describes a passenger who refuses to board, which is about choice rather than capability.
