John F Kennedy International to Lehigh Valley International JFK → ABE
76 nautical miles (87 statute miles) west on a straight line, true course 271°, about 284° magnetic at the departure end (variation 13W). At 120 knots that is 42 min at the quickest height in today's winds (4,500 ft, a 12-knot headwind), arriving about 2:31 am EDT (06:31 UTC), after sunset at the destination. Right now JFK is IFR, wind from the north-northeast (020°) at 12 knots, gusting to 21; ABE is marginal VFR, wind from the east-northeast (060°) at 9 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: 6 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 2 forecast points nearest it (JFK, AVP). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
