I concur with Lacey' s response.  We are taking the same approach.
If a credit was issued, the airfare expense is charged to a departmental account (or cleared from the sponsored award if already charged there).  We are including extensive documentation with the expense.  If the credit voucher is used in the future for travel benefiting a project funded by a sponsored award, we will journal the expense onto the award at that time.
