Travelers should use the most efficient and cost effective method of transportation available. Often times this means using a common carrier such as a train, bus, taxicab or airplane. When choosing a method of transportation several factors should be considered like; the distance traveled, the travel time, number of travelers, number of locations to be visited, and type of transportation available.
When a common carrier is available but a more expensive method is chosen without sufficient justification, reimbursement may be limited to the common carrier rate. Attach all original receipts to voucher to show means of transportation and amount paid.
If a trip is cancelled at the direction of the agency, the traveler will not be responsible for any costs incurred. If cancelled for the traveler's convenience, he/she may be responsible for any costs.
