Laughlin/Bullhead International to Seattle-Tacoma International IFP → SEA

816 nautical miles (939 statute miles) northwest on a straight line, true course 337°, about 325° magnetic at the departure end (variation 12E). At 120 knots that is 6 h 29 min at the quickest height in today's winds (39,000 ft, a 6-knot tailwind), arriving about 6:06 am PDT (13:06 UTC), after sunset at the destination. Right now IFP is VFR, wind from the southwest (230°) at 3 knots; SEA is VFR, wind from the east-southeast (110°) 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: 19 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 7 forecast points nearest it (LAS, ELY, BAM, LKV, RDM, YKM, 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.
