San Diego International to Spokane International SAN → GEG
894 nautical miles (1,029 statute miles) north on a straight line, true course 359°, about 348° magnetic at the departure end (variation 11E). At 120 knots that is 5 h 23 min at the quickest height in today's winds (24,000 ft, a 46-knot tailwind), arriving about 4:05 am PDT (11:05 UTC), after sunset at the destination. 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: 833 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 8 forecast points nearest it (SAN, ONT, WJF, BIH, BAM, BOI, LWS, GEG). 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.

Sunset at SAN 6:19 pm PDT (01:19 UTC), at GEG 6:08 pm PDT (01:08 UTC) (civil twilight ends 6:38 pm PDT (01:38 UTC)). At 120 knots the arrival at GEG is before sunrise there (7:04 am PDT (14:04 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
