Which code indicates a passenger is traveling with their own wheelchair?

The correct code that indicates a passenger is traveling with their own wheelchair is WCMP. This code is specifically used for passengers who require the use of their personal wheelchair during travel, which helps ensure that appropriate accommodations are made for their needs.

The other options represent different situations and passenger categories. WCHR is used for passengers who require assistance but do not bring their own wheelchair, indicating that they will require a wheelchair provided by the service. SVAN refers to an individual who is traveling with a service animal, signifying a different type of accommodation necessary for their journey. UMNR stands for unaccompanied minor, which designates a child traveling alone and requires special handling procedures without reference to mobility issues. Thus, WCMP is the specific code for a passenger with their own wheelchair, making it the correct choice in this context.
