San Francisco International to Laramie Regional SFO → LAR
804 nautical miles (925 statute miles) east on a straight line, true course 069°, about 055° magnetic at the departure end (variation 14E). At 120 knots that is 4 h 52 min at the quickest height in today's winds (34,000 ft, a 45-knot tailwind), arriving about 6:35 am MDT (12:35 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: 2 flights in the DOT's last twelve reported months, the route's page.

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 9 forecast points nearest it (SFO, SAC, RNO, BIH, BAM, ELY, SLC, RKS, DEN). 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 SFO 6:35 pm PDT (01:35 UTC), at LAR 6:25 pm MDT (00:25 UTC) (civil twilight ends 6:52 pm MDT (00:52 UTC)). At 120 knots the arrival at LAR is before sunrise there (7:10 am MDT (13:10 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.
