First it is important to work with your travel vendors to obtain either a refund or travel voucher/credit. If you receive a refund, it will not be necessary to reimburse. If you obtain a voucher/credit and you did not purchase through one of the university’s preferred travel providers, you will need to notify your department budget representative to let them know you have a voucher toward a future trip. The university will reimburse you for the cost of the original flight. If you purchased through one of the university’s preferred travel providers, they will work with you on tracking unused tickets/vouchers.
