AIRLINE RESERVATION CHANGES
When an involuntary airline reservation change results in additional reimbursable cost (delayed flight requiring overnight hotel and meals), you should attach a note of explanation to the Travel Voucher.

If you must make voluntary changes to your travel arrangements while en route, make the necessary change and attach a note of explanation to the Travel Voucher when you file for reimbursement.  The University will not reimburse the fees resulting from the change if the change is for personal reasons.
