Detroit Metro Wayne County to Luis Munoz Marin International DTW → SJU
1,679 nautical miles (1,933 statute miles) southeast on a straight line, true course 143°, about 150° magnetic at the departure end (variation 7W). At 120 knots that is 14 h 07 min at the quickest height in today's winds (5,500 ft, a 1-knot headwind), arriving about 10:57 am AST (14:57 UTC). Right now DTW is marginal VFR, wind from the northwest (310°) at 4 knots; SJU is VFR, wind from the southeast (130°) at 3 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 706 flights in the DOT's last twelve reported months, the route's page.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
