The FTPDA will be based on the most current publications of the U.S. Department of State maximum travel per diem allowances for foreign areas. The daily FTPDA will be 100 percent of the listed M & IE rate in the referenced publication. The actual costs of lodging plus applicable tax and service charge will be reimbursed to the traveler.
