Lewiston/Nez Perce County to Laughlin/Bullhead International LWS → IFP
683 nautical miles (786 statute miles) south on a straight line, true course 170°, about 155° magnetic at the departure end (variation 15E). At 120 knots that is 5 h 53 min at the quickest height in today's winds (5,500 ft, a 4-knot headwind), arriving about 4:41 am MST (11:41 UTC), after sunset at the destination. Right now LWS is VFR, wind calm; IFP is VFR, wind from the southwest (220°) at 6 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.

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 eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 5 forecast points nearest it (LWS, BOI, BAM, ELY, LAS). 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.
