Jackson Hole Airport to Los Angeles International JAC → LAX
682 nautical miles (784 statute miles) southwest on a straight line, true course 214°, about 201° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 37 min at the quickest height in today's winds (4,500 ft, a 17-knot headwind), arriving about 12:26 am PDT (07:26 UTC), after sunset at the destination. Right now JAC is marginal VFR, wind calm; LAX is VFR, wind from the west-southwest (240°) at 9 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: 1,325 flights in the DOT's last twelve reported months, the route's page.

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 5 forecast points nearest it (PIH, SLC, ELY, LAS, WJF). 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.
