Gerald R Ford International to Luis Munoz Marin International GRR → SJU
1,771 nautical miles (2,038 statute miles) southeast on a straight line, true course 140°, about 146° magnetic at the departure end (variation 6W). At 120 knots that is 13 h 31 min at the quickest height in today's winds (24,000 ft, a 11-knot tailwind), arriving about 12:14 pm AST (16:14 UTC). Right now GRR is VFR, wind from the south (190°) at 6 knots; SJU is VFR, wind calm. 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: 2 flights in the DOT's last twelve reported months, the route's page.

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 9 forecast points nearest it (MKG, FWA, CMH, CRW, ROA, RDU, ILM, MLB, MIA). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
