Denver International to Fairbanks International DEN → FAI

2,107 nautical miles (2,425 statute miles) northwest on a straight line, true course 330°, about 322° magnetic at the departure end (variation 8E). At 120 knots that is 16 h 51 min at the quickest height in today's winds (10,500 ft, a 5-knot tailwind), arriving about 9:23 am AKDT (17:23 UTC). Right now DEN is VFR, wind from the south-southeast (160°) at 17 knots, gusting to 23; FAI is VFR, wind from the west-southwest (250°) at 4 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: 253 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 8 forecast points nearest it (DEN, BFF, LND, BIL, GTF, GPI, GEG, SEA). 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.
