Long Island Mac Arthur Airport to Laguardia Airport ISP → LGA
35 nautical miles (40 statute miles) west on a straight line, true course 268°, about 282° magnetic at the departure end (variation 14W). At 120 knots that is 15 min at the quickest height in today's winds (4,500 ft, a 16-knot tailwind), arriving about 10:09 pm EDT (02:09 UTC), after sunset at the destination. Right now ISP is IFR, wind from the northeast (050°) at 10 knots, gusting to 17; LGA is IFR, wind from the northeast (050°) at 19 knots, gusting to 31. 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: 3 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed
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 1 forecast point nearest it (JFK). A plus sign is a headwind, a minus sign a tailwind.

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.
