Jet lag plan
Bridgetown and Miami share the same time zone.
About 2,571 km northwest · approximately 4-hour non-stop flight · a long-haul flight.
The route from Bridgetown, Barbados to Miami, United States covers roughly 2,571 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 4 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.
Bridgetown is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round. Miami is in the subtropics. Day length varies by roughly two hours between summer and winter; light remains a reliable circadian cue most of the year.
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 9 hours. In Bridgetown that window runs 09:00 to 18:00; in Miami it is 09:00 to 18:00. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
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).
The great-circle distance from Bridgetown to Miami is about 2,571 kilometres. A typical non-stop flight takes around 4 hours at standard cruise speed; routes with connections add two to four hours.
Bridgetown and Miami share the same time zone, so there is no clock offset on this route.
No circadian shift is required between these two cities.
For a shift of 0 hours, 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.
For a shift under two hours, pre-trip adjustment is usually not worth the effort.
Chronotype does not affect adjustment on a same-time-zone route.
