Jackson Hole Airport to Phoenix Sky Harbor International JAC → PHX
614 nautical miles (706 statute miles) south on a straight line, true course 186°, about 173° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 16 min at the quickest height in today's winds (7,500 ft, a 22-knot headwind), arriving about 12:23 pm MST (19:23 UTC). Right now JAC is VFR, wind variable at 4 knots; PHX is VFR, wind from the south (170°) at 8 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: 3 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed
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 (PIH, SLC, BCE, PRC, PHX). A plus sign is a headwind, a minus sign a tailwind.

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.
