Air Reservations

Travel by commercial airlines is limited to the lowest priced airfare to meet the business requirements. If possible, the airline ticket should be purchased at least seven days in advance in order to receive the advance ticket pricing offered by the airlines. ORAU prefers to purchase your airline ticket. If you purchase the ticket, however, you should include the cost of the ticket on the Preapproval Request. All ORISE foreign travel tickets must be purchased by ORAU.
