[Request for Decision Concerning FAA Employee's Subsistence Expenses Claim]

The Federal Aviation Administration (FAA) requested a decision on whether it could reimburse an employee for travel costs that were less than the cost of common-carrier travel when the employee charged the travel time to annual leave. GAO held that FAA could not reimburse the employee for expenses incurred while traveling by private vehicle when he charged excess travel time to annual leave, even if the total travel costs were less than the total costs of travel by common carrier. Accordingly, the claim was denied.
