Northern Colorado Regional to Spokane International FNL → GEG
689 nautical miles (793 statute miles) northwest on a straight line, true course 313°, about 304° magnetic at the departure end (variation 9E). At 120 knots that is 5 h 11 min at the quickest height in today's winds (8,500 ft, a 13-knot tailwind), arriving about 12:23 am PDT (07:23 UTC), after sunset at the destination. Right now FNL is VFR, wind from the north (350°) at 3 knots; GEG is VFR, wind from the northeast (040°) at 11 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: 2 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 (DEN, RKS, LND, DLN, LWS, GEG). 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.
