Jackson Hole Airport to John Wayne/Orange County JAC → SNA
683 nautical miles (786 statute miles) southwest on a straight line, true course 212°, about 199° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 27 min at the quickest height in today's winds (4,500 ft, a 14-knot headwind), arriving about 1:27 pm PDT (20:27 UTC). 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 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
