John Wayne/Orange County to Prescott Rgnl/Ernest A Love Field SNA → PRC
277 nautical miles (319 statute miles) east on a straight line, true course 076°, about 064° magnetic at the departure end (variation 12E). At 120 knots that is 1 h 38 min at the quickest height in today's winds (34,000 ft, a 50-knot tailwind), arriving about 6:47 pm MST (01:47 UTC), after sunset at the destination. Right now SNA is VFR, wind from the south-southwest (200°) at 7 knots; PRC is marginal VFR, wind from the south-southwest (200°) at 15 knots, gusting to 24. 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 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.
