03 · Travel Segments

Travel Legs & Waiting Time 5 CFR 550.1404(b) · OPM Fact Sheet

Enter each leg of travel using local time where you are — select the local time zone for each segment and the calculator will automatically convert everything to your point-of-first-departure time zone per OPM guidance. Travel status ends upon arrival at the TDY worksite or lodging (whichever first) and resumes upon departure (whichever last). Time at the TDY location does not count.

04 · JTR Adjustments & Exclusions

Required Deductions & Special Circumstances 5 CFR 550.1404 · JTR Para. 030501

Commute Offset (home → airport, within ODS limits)

Travel from home to airport WITHIN your official duty station limits = commuting time, NOT creditable. Enter minutes to deduct. (5 CFR 550.1404(d))

Meal Periods During Travel (minutes)

Per DoD/OPM Q&A #8: bona fide meal periods are NOT creditable. Deduct uninterrupted meal time. (DoDI 1400.25 V550)

Extended Waiting Time to Exclude

hours

minutes

Unusually long waits where employee is free to rest/sleep are NOT creditable. Domestic: waits beyond ~2 hrs may be excluded; International: beyond ~3 hrs. Agency has sole discretion. (5 CFR 550.1404(b)(2))

Other Non-Creditable Time (minutes)

Any other personal-use time, extended layovers, voluntary stopovers, etc.

Special Circumstances

Travel on Federal Holiday

Holiday hours are still compensable as holiday pay; separate TC code applies. Travel comp time may still be earned for time outside regular working hours on a holiday. (OPM Q&A #36)

Employee Driving (not a passenger)

Driving as the required operator still qualifies as travel status for travel comp time purposes.

Employee Performed Official Work En Route

If work was performed during travel (e.g., reading reports, writing on flight), that time is compensable as regular work — NOT travel comp time. Exclude that time from segments above.

Work Schedule Adjusted to Capture Travel Time

Agency cannot change your administrative workweek solely to convert travel time to regular pay and reduce comp time eligibility. (OPM guidance / 5 CFR 550.1403)

Rounding Method: Rounds to nearest 15 minutes per DoDI 1400.25 V550
