Long Island Mac Arthur Airport to Witham Field ISP → SUA
890 nautical miles (1,024 statute miles) southwest on a straight line, true course 206°, about 220° magnetic at the departure end (variation 14W). At 120 knots that is 7 h 07 min at the quickest height in today's winds (8,500 ft, a 5-knot tailwind), arriving about 3:04 pm EDT (19:04 UTC). Right now ISP is IFR, wind from the north-northeast (020°) at 13 knots, gusting to 21; SUA is VFR, wind from the north-northwest (330°) 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.

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 6 forecast points nearest it (JFK, ACY, ORF, ILM, CHS, MLB). 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.
