Anchorage to Los Angeles: Route overview
This medium-haul route from Anchorage (ANC) to Los Angeles (LAX) covers 3,771 km in approximately 4h 56m to 5h 40m, crossing 1 time zone eastbound. With only a 1-hour time difference, most travelers adjust within a day, though the medium-haul journey may still cause travel fatigue. The route transitions between subarctic and subtropical climate zones, so expect a significant change in daylight duration and intensity that influences your circadian adjustment strategy.
What makes the Anchorage–Los Angeles route different
With only 1 hour of time difference, this route sits at the threshold where jet lag is barely noticeable for most travelers. The bigger factor is likely the 4h 56m to 5h 40m flight duration itself and any associated sleep deprivation.
Arrival strategy for Los Angeles
Arriving in Los Angeles after a 1-hour eastward shift, your body will think it is 1 hours earlier than the local clock shows. If you arrive in the morning, push through fatigue and get outside in bright daylight. If you arrive in the evening, eat a light meal and go to bed at the local time — you may wake early, but resist getting up until at least 05:00.
Circadian rhythm analysis: Anchorage → Los Angeles
When you arrive in Los Angeles, your circadian rhythm is still running on Anchorage time. At 09:00 Los Angeles time, your body clock reads 08:00 — already a reasonable waking hour. The disruption is moderate, and you should be able to function with some effort. By 22:00 local time (when you should sleep), your body reads 21:00 — approaching your natural evening. Sleep onset should be achievable with proper wind-down routine. Your circadian system adjusts at roughly 1 hour per day, so expect 1 day for full alignment.
Your body clock in Los Angeles (day 1)
How your body clock maps to local time upon arrival, before any adjustment.
| Los Angeles Time | Your Body Clock (Anchorage) | How You Feel | Recommendation |
|---|---|---|---|
| 06:00 | 05:00 | Early wake phase. Groggy, low energy. | Light physical activity helps. Coffee is acceptable if 8+ hours before target bedtime. |
| 09:00 | 08:00 | Morning alertness building. Moderate energy. | Good window for bright light exposure if adjusting eastward. |
| 12:00 | 11:00 | Peak morning alertness on body time. | Productive window. Use this energy for important tasks. |
| 15:00 | 14:00 | Post-lunch dip. Moderate energy. | Brief 20-min nap acceptable if severely fatigued. Avoid long naps. |
| 18:00 | 17:00 | Afternoon alertness on body time. | Good window for light exposure if adjusting westward. |
| 21:00 | 20:00 | Evening wind-down. Melatonin starting to rise. | Dim lights and avoid screens if you need to stay awake longer. |
| 00:00 | 23:00 | Natural sleep window on body time. | Ideal time to sleep if it aligns with local night. If not, use bright light to delay. |
| 03:00 | 02:00 | Deep sleep phase. Intense drowsiness likely. | If awake, use bright light to push clock forward. Avoid driving or complex tasks. |
Pre-departure preparation

Seasonal and climate factors
Flight times between Anchorage and Los Angeles can vary by 15–30 minutes seasonally due to shifting wind patterns along this medium-haul corridor. Los Angeles at 34°N experiences moderate seasonal daylight variation. Summer offers longer evenings useful for westward adjustment, while winter's earlier sunsets support eastward adjustment schedules.
How the Anchorage–Los Angeles flight time is estimated
The 4h 56m to 5h 40m estimate for Anchorage to Los Angeles is derived from the 3,771-km great-circle distance. Medium-haul flights balance cruise and non-cruise phases, achieving effective speeds of 780–850 km/h. An additional 30–50 minutes accounts for taxi, takeoff, climb, descent, approach, and taxi at both ANC and LAX. Actual routing through controlled airspace may add 3–8% distance beyond the great-circle path due to air traffic corridors and restricted zones along the way.
Wind patterns and flight duration
Prevailing winds along the Anchorage–Los Angeles corridor have a moderate effect on flight time. The general west-to-east flow of upper-level winds at these latitudes provides a slight tailwind advantage.
