Henderson Executive to Boeing Fld/King County International HND → BFI
764 nautical miles (879 statute miles) north on a straight line, true course 338°, about 325° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 04 min at the quickest height in today's winds (39,000 ft, a 6-knot tailwind), arriving about 12:53 am PDT (07:53 UTC), after sunset at the destination. Right now HND is VFR, wind from the south (190°) at 12 knots; BFI is VFR, wind from the northwest (310°) 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: 3 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 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 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.
