Bozeman Yellowstone International to Hollywood Burbank Airport BZN → BUR
769 nautical miles (885 statute miles) southwest on a straight line, true course 208°, about 195° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 38 min at the quickest height in today's winds (4,500 ft, a 4-knot headwind), arriving about 10:48 am PDT (17:48 UTC). Right now BZN is marginal VFR, wind from the southwest (230°) at 3 knots; BUR is marginal VFR, wind from the west-southwest (250°) at 5 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: 3 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 08:00–15:00 UTC · at 120 knots true airspeed
The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 5 forecast points nearest it (DLN, PIH, ELY, BIH, WJF). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
