Getting different questions as to whether the FTR and JTR are applicable to contractor's. If not what regulations are applicable?
As we do not have all of the facts particular to your contract, program, and situation, we highly recommend you consult your Contracting Officer and agency specific guidance. In terms of regulations, see
FAR Part 31 Contract Cost Principles and Procedures, specifically FAR 31.205-46 --Travel Costs, for treatment of costs for transportation, lodging, meals, and incidental expenses.
