Luis Munoz Marin International to Edgar County SJU → PRG
1,700 nautical miles (1,956 statute miles) northwest on a straight line, true course 323°, about 334° magnetic at the departure end (variation 11W). At 120 knots that is 15 h 19 min at the quickest height in today's winds (4,500 ft, a 9-knot headwind), arriving about 10:33 pm CDT (03:33 UTC), after sunset at the destination. Right now SJU is VFR, wind variable at 3 knots; PRG is VFR, wind from the south (190°) at 4 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: 1 flights in the DOT's last twelve reported months, the route's page.

The westbound cruising heights for this course (VFR: even 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 (MIA, MLB, CHS, CAE, GSP, TRI, TYS, LOU, IND). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
