North Platte Rgnl/Lee Bird Field to Jack Northrop Fld/Hawthorne Municipal LBF → HHR
943 nautical miles (1,085 statute miles) west on a straight line, true course 248°, about 242° magnetic at the departure end (variation 6E). At 120 knots that is 9 h 43 min at the quickest height in today's winds (8,500 ft, a 23-knot headwind), arriving about 4:28 am PDT (11:28 UTC), after sunset at the destination. 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.
