Los Angeles International to Tri-Cities Airport LAX → PSC
741 nautical miles (852 statute miles) north on a straight line, true course 358°, about 346° magnetic at the departure end (variation 12E). At 120 knots that is 5 h 22 min at the quickest height in today's winds (34,000 ft, a 18-knot tailwind), arriving about 12:15 am PDT (07:15 UTC), after sunset at the destination. Right now LAX is VFR, wind from the west-southwest (240°) at 8 knots; PSC is VFR, wind from the northeast (040°) at 11 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: 715 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.
