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 TAR. All ORISE foreign travel tickets must be purchased by ORAU.

Note: If ORAU is purchasing airfare for you, you must reply to ORAU Travel Central with your approval of the tentative itinerary before an electronic ticket can be purchased. Any delay in the approval of the itinerary may cause an increase in the actual airfare at the time the ticket is purchased (airfares tend to change daily and sometimes even several times a day).
