What questions should an operator ask when boarding a passenger with a service animal?

The appropriate questions for an operator to ask when boarding a passenger with a service animal focus on confirming the animal's purpose and functionality. In this case, inquiring whether the animal is a service animal and what specific services it provides is crucial. This ensures that operators can accommodate the passenger accordingly and comply with regulations surrounding service animals.

Service animals are not pets; they are highly trained to assist individuals with disabilities. Understanding their role helps the operator to provide necessary support and facilitate a smooth boarding process. These questions are respectful and relevant, eliminating any ambiguity about the animal's function while respecting the passenger’s right to privacy concerning personal matters related to the animal’s training or the passenger’s disability.

In contrast, the other options focus on topics that are not appropriate or relevant for verifying the status of a service animal. For example, asking about the pet status or training methods does not align with the protocols in place for service animals. Queries that involve petting the animal or discussing its breed and duration of presence also do not contribute to understanding the animal's service role.
