About the Port of Spain → Washington route
The route from Port of Spain, Trinidad and Tobago to Washington, United States covers roughly 3,498 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 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.
Port of Spain is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round. Washington 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.
