Boulder City Municipal to Merrill Field BVU → MRI
2,011 nautical miles (2,315 statute miles) northwest on a straight line, true course 330°, about 319° magnetic at the departure end (variation 11E). At 120 knots that is 16 h 46 min at the quickest height in today's winds (4,500 ft, no wind along the track), arriving about 3:23 pm AKDT (23:23 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: 1,659 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.
