The authorized travel days are calculated using 350 miles/day (based on the DTOD distance between the authorized points) for an employee or member. 1 travel day is allowed for each 350 miles of official distance of ordered travel.
1 One travel day is allowed for each 350 miles using the most direct route.  If the additional distance is over 50 miles after dividing the total mileage by 350, one additional travel day is allowed.
