John Wayne/Orange County to Jackson Hole Airport SNA → JAC
683 nautical miles (786 statute miles) northeast on a straight line, true course 027°, about 015° magnetic at the departure end (variation 12E). At 120 knots that is 3 h 33 min at the quickest height in today's winds (30,000 ft, a 72-knot tailwind), arriving about 12:13 pm MDT (18:13 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.

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 5 forecast points nearest it (ONT, LAS, ELY, SLC, PIH). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
