About the Mexico City → Portland route
The route from Mexico City, Mexico to Portland, United States covers roughly 3,617 kilometres in a northwest direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 5.2 hours. Both cities sit in the northern hemisphere, so the seasonal direction of daylight (longer days in June, shorter in December) matches between origin and destination.
Mexico City is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round. Portland is in the temperate zone. Day length varies by four to six hours between summer and winter, so the season of your trip materially affects available morning and evening light.
Business-hours overlap
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 8 hours. In Mexico City that window runs 10:00 to 18:00; in Portland it is 09:00 to 17:00. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
Daylight saving on this route
Only one of the two cities observes daylight saving time, so the offset between them shifts by one hour twice a year. If you have recurring meetings on this route, double-check the local time around the DST transitions (March and October/November in the northern hemisphere).
Your chronotype on this route
If you are a lark (morning type): Westward travel is the easier direction and larks usually feel close to baseline within 2 days. The risk for larks is overshooting: stay up later than you feel like at the destination for the first two nights to avoid waking before local sunrise.
If you are a night owl (evening type): Westward travel suits owls because the body prefers delaying over advancing. A 1-hour westward shift typically clears in 1 days. Stay outside in the evening light at the destination and avoid early-morning bright light for the first three days.

Is jet lag worse flying east or west on this route?
Westward travel — which this route is — is the easier direction. Your body delays its clock, which is closer to its natural tendency. Most travellers clear a 1-hour westward shift in 1 days.
Should I take melatonin for the Mexico City → Portland trip?
For a shift of 1 hour, melatonin offers little benefit beyond what consistent light exposure already provides. The Cochrane review on jet-lag melatonin shows the strongest effects on shifts of five hours or more.
Do I need a pre-trip schedule shift for Mexico City → Portland?
For a shift under two hours, pre-trip adjustment is usually not worth the effort.
What chronotype handles this route best?
Owls (evening types) recover faster on westward routes because the body prefers delaying over advancing. Larks may overshoot — they should stay up later than they feel like at the destination for the first two nights.
