| | When orders direct travel by a specific mode of transportation on a "when available" basis but authorize another mode of transportation for the member's convenience at no additional expense to the Government, and the mode of travel directed is available but not used, per diem allowances or AEAs are payable for travel performed not to exceed the per diem or AEA which would have been payable if the directed mode of transportation had been used.� When the directed mode of transportation isn�t available or the orders don�t specify any mode of transportation, per diem or AEA is computed as though the mode of transportation used was directed, the total per diem or AEA payable not to exceed that payable for constructive travel over a usually traveled route by air or surface common carrier, whichever more nearly meets the requirements of the orders and is more economical to the Government.� In determining constructive travel, the travel allowances are based on the carrier's required check-in time plus travel time from home, office, or place travel actually began, and the carrier's scheduled arrival time at the terminal plus travel time to home, office, or place travel actually ended. |
