Claim for Additional Per Diem Incident to Travel From Official Duty Station

An employee was authorized prior to departure on annual leave to attend a meeting near his leaving point. The employee claimed per diem for traveltime to and from his temporary duty station. Travel authorization was ambiguous because it stated "travel at no cost to Government," but authorized per diem. Since the employee had to begin travel 2 days before his leave started, he may be allowed per diem for traveltime to and from the temporary duty station. The claim for additional per diem may be allowed if otherwise proper.
