Rick Husband Amarillo International to San Francisco International AMA → SFO

1,007 nautical miles (1,159 statute miles) west on a straight line, true course 284°, about 276° magnetic at the departure end (variation 8E). At 120 knots that is 8 h 28 min at the quickest height in today's winds (4,500 ft, a 1-knot headwind), arriving about 3:11 am PDT (10:11 UTC), after sunset at the destination. Right now AMA is VFR, wind from the south (170°) at 14 knots; SFO is VFR, wind from the west-southwest (240°) at 13 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: 5 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 9 forecast points nearest it (AMA, TCC, ABQ, FMN, BCE, LAS, BIH, FAT, SFO). 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.
