Flagstaff Pulliam Airport to San Francisco International FLG → SFO
538 nautical miles (619 statute miles) west on a straight line, true course 289°, about 279° magnetic at the departure end (variation 10E). At 120 knots that is 4 h 29 min at the quickest height in today's winds (4,500 ft, no wind along the track), arriving about 8:59 pm PDT (03:59 UTC), after sunset at the destination. Right now FLG is IFR, wind from the south-southwest (200°) at 16 knots, gusting to 30; SFO is VFR, wind from the west-southwest (250°) at 15 knots, gusting to 23. 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: 1 flights in the DOT's last twelve reported months, the route's page.

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.
