Airfare which is direct-billed requires the originating city be Chattanooga. Travelers wishing to fly out of alternate airports must purchase the ticket and document cost savings with a quote for flying out of Chattanooga, and must include mileage/shuttle to the alternate airport. Billing of airfare for guest must list Chattanooga as the destination city. Using alternate airports usually includes mileage or shuttle to airport and additional meal reimbursement for extended travel time, not saving the university money. Policy states;

Airfare involving additional destinations for personal reasons, business or first class tickets, or leaving from a destination other than the traveler’s official station may not be purchased through direct bill. (F10705-Travel, item 26.d)
