John F Kennedy International to Ted Stevens Anchorage International JFK → ANC
2,934 nautical miles (3,377 statute miles) northwest on a straight line, true course 322°, about 335° magnetic at the departure end (variation 13W). At 120 knots that is 23 h 28 min at the quickest height in today's winds (4,500 ft, a 5-knot tailwind), arriving about 9:12 pm AKDT (05:12 UTC), after sunset at the destination. Right now JFK is IFR, wind from the north-northeast (020°) at 12 knots, gusting to 21; ANC is VFR, wind from the south-southeast (150°) 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: 3,504 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 02:00–09:00 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 10 forecast points nearest it (JFK, AVP, SYR, BUF, TVC, INL, MOT, GGW, GPI, SEA). 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.
