What is the role of an Authorizing Official (AO) in regards to travel?

The role of an Authorizing Official (AO) specifically includes the responsibility of approving travel requests and expenses. The AO ensures that the travel is necessary for official business and complies with relevant agency policies and regulations. By approving these requests, the AO not only validates the purpose and intent of the travel but also engages in the oversight to ensure proper use of public funds.

The other roles listed contribute to the overall travel process but do not fall under the purview of the AO. Arranging travel logistics involves planning and managing specifics like flights and accommodations, which can be handled by travel coordinators or assistants. Serving as the traveler's representative can pertain to various individuals in different contexts, but the AO's primary responsibility centers on approval rather than representation. Handling financial transactions is typically the role of the finance department or a financial officer, rather than the AO, who focuses on authorization rather than transactional management.
