(a) General. Subject to the conditions specified in this subpart, an agency must credit an employee with compensatory time off for time in a travel status if—

(1) The employee is required to travel away from the official duty station; and

(2) The travel time is not otherwise compensable hours of work under other legal authority.

(b)(1) Travel status. Time in a travel status includes the time an employee actually spends traveling between the official duty station and a temporary duty station, or between two temporary duty stations, and the usual waiting time that precedes or interrupts such travel, subject to the exclusion specified in paragraph (b)(2) of this section and the requirements in paragraph (c), (d) and (e) of this section. Time spent at a temporary duty station between arrival and departure is not time in a travel status. Time in a travel status ends when the employee arrives at the temporary duty worksite or his or her lodging in the temporary duty station, wherever the employee arrives first. Time in a travel status resumes when an employee departs from the temporary duty worksite or his or her lodging in the temporary duty station, from whichever the employee departs last. Travel time in connection with an employee's permanent change of station is not time in a travel status. Determinations regarding what is creditable as “usual waiting time” are within the sole and exclusive discretion of the employing agency.

(2) If an employee experiences an extended (i.e., not usual) waiting time between actual periods of travel during which the employee is free to rest, sleep, or otherwise use the time for his or her own purposes, the extended waiting time is not creditable as time in a travel status.

(c) Travel between home and a temporary duty station. (1) If an employee is required to travel directly between his or her home and a temporary duty station outside the limits of the employee's official duty station, the travel time is creditable as time in a travel status if otherwise qualifying under this subpart. However, the agency must deduct from such travel hours the time the employee would have spent in normal home-to-work or work-to-home commuting.

(2) In the case of an employee who is offered one mode of transportation and who is permitted to use an alternative mode of transportation, or who travels at a time or by a route other than that selected by the agency, the agency must determine the estimated amount of time in a travel status the employee would have had if the employee had used the mode of transportation offered by the agency or traveled at the time or by the route selected by the agency. In determining time in a travel status under this subpart, the agency must credit the employee with the lesser of the estimated time in a travel status or the actual time in a travel status.

(3) In the case of an employee who is on a multiple-day travel assignment and who chooses, for personal reasons, not to use temporary lodgings at the temporary duty station, but to return home at night or on a weekend, only travel from home to the temporary duty station on the 1st day and travel from the temporary duty station to home on the last day that is otherwise qualifying as time in a travel status under this subpart is mandatorily creditable (subject to the deduction of normal commuting time). Travel to and from home on other days is not creditable travel time unless the agency, at its discretion, determines that credit should be given based on the net savings to the Government from reduced lodging costs, considering the value of lost labor time attributable to compensatory time off. The dollar value of an hour of compensatory time off for this purpose is equal to the employee's hourly rate of basic pay as defined in § 550.103.

(d) Time spent traveling to or from a transportation terminal as part of travel away from the official duty station. If an employee is required to travel between home and a transportation terminal (e.g., airport or train station) within the limits of his or her official duty station as part of travel away from that duty station, the travel time outside regular working hours to or from the terminal is considered to be equivalent to commuting time and is not creditable time in a travel status. If the transportation terminal is outside the limits of the employee's official duty station, the travel time to or from the terminal outside regular working hours is creditable as time in a travel status, but is subject to an offset for the time the employee would have spent in normal home-to-work or work-to-home commuting. If the employee travels between a worksite and a transportation terminal, the travel time outside regular working hours is creditable as time in a travel status, and no commuting time offset applies.

(e) Travel involving two or more time zones. When an employee's travel involves two or more time zones, the time zone from the point of first departure must be used to determine how many hours the employee actually spent in a travel status for the purpose of accruing compensatory time off.
