About the Santiago → Port of Spain route

The route from Santiago, Chile to Port of Spain, Trinidad and Tobago covers roughly 5,000 kilometres in a due north direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 6.7 hours. This route crosses the equator. The destination's season is reversed relative to the origin, which can amplify the perceived disorientation of jet lag — your body lands not just in a different clock but in a different daylight regime.

Santiago 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. 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.

Business-hours overlap

Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 9 hours. In Santiago that window runs 09:00 to 18:00; in Port of Spain 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.

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).
