Jackson Hole Airport to San Luis Obispo County Regional JAC → SBP
680 nautical miles (782 statute miles) southwest on a straight line, true course 226°, about 213° magnetic at the departure end (variation 13E). At 120 knots that is 5 h 52 min at the quickest height in today's winds (4,500 ft, a 4-knot headwind), arriving about 11:42 pm PDT (06:42 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: 3 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.
