Monterey Regional to Bozeman Yellowstone International MRY → BZN
732 nautical miles (842 statute miles) northeast on a straight line, true course 038°, about 023° magnetic at the departure end (variation 15E). At 120 knots that is 4 h 14 min at the quickest height in today's winds (34,000 ft, a 53-knot tailwind), arriving about 1:54 am MDT (07:54 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 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.

Sunset at MRY 6:35 pm PDT (01:35 UTC), at BZN 6:44 pm MDT (00:44 UTC) (civil twilight ends 7:14 pm MDT (01:14 UTC)). At 120 knots the arrival at BZN is before sunrise there (7:36 am MDT (13:36 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
