Baltimore/Washington International Thurgood Marshall to Luis Munoz Marin International BWI → SJU
1,363 nautical miles (1,569 statute miles) southeast on a straight line, true course 153°, about 164° magnetic at the departure end (variation 11W). At 120 knots that is 12 h 10 min at the quickest height in today's winds (11,500 ft, a 8-knot headwind), arriving about 8:48 am AST (12:48 UTC). Right now BWI is IFR, wind from the northeast (040°) at 8 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: 2,275 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.
