Spokane International to San Diego International GEG → SAN
894 nautical miles (1,029 statute miles) south on a straight line, true course 179°, about 165° magnetic at the departure end (variation 14E). At 120 knots that is 7 h 23 min at the quickest height in today's winds (5,500 ft, a 1-knot tailwind), arriving about 12:11 am PDT (07:11 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.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from GEG.

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 8 forecast points nearest it (GEG, LWS, BOI, BAM, BIH, WJF, ONT, SAN). 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.

Daylight
Sunset at GEG 6:08 pm PDT (01:08 UTC), at SAN 6:19 pm PDT (01:19 UTC) (civil twilight ends 6:44 pm PDT (01:44 UTC)). At 120 knots the arrival at SAN is before sunrise there (6:50 am PDT (13:50 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.
