Expenses incurred in necessary travel on official business for the authority by the members, agents and employees are reimbursable to the amount actually spent or the established limits, whichever is lower. When using a common carrier, such as a bus, train or airplane, reimbursable transportation expense will be approved only for the coach rate and not the first class rate, unless the higher rate can be justified.
