Every effort should be made to qualify for the lowest logical airfares by planning trips and ordering tickets in advance and by allowing flexibility in arrival and departure times. Local approved travel agents will book non-refundable tickets whenever substantial savings are available. If a business reason requires a change to a non-refundable ticket, the re-issuance fees are reimbursable. Any unused tickets must be returned to the local approved travel agents and may be used for future travel. These tickets are subject to the same restrictions as the original ticket with a minimal penalty. The penalty fee is a company expense.
