Claim for Per Diem During Active Duty

An individual has claimed that he is entitled to per diem for certain periods he served on active duty in the Air Force. His tour was extended a number of times, and the total length of time he served was approximately 65 weeks. He was paid per diem for over 400 days and also transportation expenses for his round-trip travel to Richards-Gebaur Air force Base, Missouri. He has claimed he is also entitled to per diem for 32 additional days. In a prior decision, GAO determined that because there was no clear indication of the reasons for the extensions of the period of active duty in the documentation pertaining to the case, GAO could make no determination as to whether or not the individual was entitled to per diem for this period. GAO determined that in this case, before the claim can be paid, the reasons for the extensions of his tour will have to be determined.
