Mileage in Lieu of Out-of-State Air Travel
Travelers may request a mileage reimbursement for personal reasons even though air travel is the appropriate form of transportation, if such costs shall not exceed the cost of airfare.
Airfare cost is based on the lowest regular coach fare available, plus transportation costs to and from the airport and estimated parking fees incurred, had the traveler opted to travel by air. The regular coach fare must be obtained from the university’s designated travel agency.
To support the reimbursement, travelers should use the T-1 Transportation Cost Equivalency form.
Personally Owned Vehicles
Travelers may use a personally owned vehicle for university business if it is:
- More cost effective than renting a car, taking a taxi, or other transportation methods, OR
- Saves time.
Those authorized to travel via a personally owned vehicle will be reimbursed in accordance with the standard mileage rate, which includes automobile expenses such as fuel, lubrication, towing charges, repairs, replacements, tires, depreciation, insurance, etc. These and other automobile expenses will not be reimbursed.
When two or more persons traveling on university business share a personally owned vehicle, only the driver may claim reimbursement for mileage.
Parking and toll expenses are reimbursable when properly documented on the Expense Report. Receipts are the primary form of documentation, but the Tollsmart Calculator may also be used.
