New York Stewart International to Cyril E King Airport SWF → STT
1,468 nautical miles (1,689 statute miles) south on a straight line, true course 159°, about 173° magnetic at the departure end (variation 14W). At 120 knots that is 11 h 07 min at the quickest height in today's winds (11,500 ft, a 12-knot tailwind), arriving about 4:48 pm AST (20:48 UTC). Right now SWF is IFR, wind from the northeast (040°) at 6 knots; STT is VFR, wind from the east (090°) at 6 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.

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.
