Robert Gray Army Airfield to San Diego International GRK → SAN
991 nautical miles (1,140 statute miles) west on a straight line, true course 281°, about 277° magnetic at the departure end (variation 4E). At 120 knots that is 8 h 42 min at the quickest height in today's winds (4,500 ft, a 6-knot headwind), arriving about 7:25 am PDT (14:25 UTC). 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: 2 flights in the DOT's last twelve reported months, the route's page.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
