Monterey Regional to Grand Junction Regional MRY → GJT
649 nautical miles (747 statute miles) east on a straight line, true course 072°, about 057° magnetic at the departure end (variation 15E). At 120 knots that is 3 h 55 min at the quickest height in today's winds (39,000 ft, a 46-knot tailwind), arriving about 12:42 pm MDT (18:42 UTC). Right now MRY is VFR, wind from the east (100°) at 6 knots; GJT is VFR, wind from the east-southeast (120°) at 15 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: 1 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 14:00–21:00 UTC · at 120 knots true airspeed
The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 6 forecast points nearest it (SFO, FAT, BIH, ELY, BCE, GJT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
