Yampa Valley Airport to John Wayne/Orange County HDN → SNA
653 nautical miles (751 statute miles) southwest on a straight line, true course 235°, about 225° magnetic at the departure end (variation 10E). At 120 knots that is 7 h 11 min at the quickest height in today's winds (8,500 ft, a 29-knot headwind), arriving about 12:21 am PDT (07:21 UTC), after sunset at the destination. Right now HDN is VFR, wind from the southwest (220°) at 9 knots, gusting to 22; SNA is VFR, wind from the south-southwest (200°) at 7 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: 4 flights in the DOT's last twelve reported months, the route's page.

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.
