Yellowstone Airport to Palm Springs International WYS → PSP
698 nautical miles (803 statute miles) southwest on a straight line, true course 203°, about 189° magnetic at the departure end (variation 14E). At 120 knots that is 6 h 24 min at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 8:24 am PDT (15:24 UTC). Right now WYS is marginal VFR, wind calm; PSP is VFR, wind calm. 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.
