What does WCHS stand for in special service requests?

The correct answer signifies that "WCHS" specifically refers to passengers who need assistance when using a wheelchair, particularly emphasizing that they require a wheelchair during their travel but may not need comprehensive support with boarding or disembarking. The category generally applies to passengers who can walk short distances but cannot navigate the airport without a wheelchair's assistance.

Understanding this helps clarify that although the other options involve different aspects of wheelchair-related assistance, they do not accurately capture the specific service identified by the WCHS code. For example, the choice indicating complete assistance with a lift describes a broader support scenario that doesn't align with the specific usage of WCHS. Furthermore, the other options pertain to various types of assistance, but none reflect the specific service that "WCHS" provides. Thus, recognizing WCHS as a designation for passengers who primarily require wheelchair assistance without additional needs aligns perfectly with the standards for Special Service Requests in air travel.
