Boulder City Municipal to Skwentna Airport BVU → SKW
2,068 nautical miles (2,380 statute miles) northwest on a straight line, true course 331°, about 320° magnetic at the departure end (variation 11E). At 120 knots that is 17 h 41 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 8:50 pm AKDT (04:50 UTC), after sunset at the destination. Right now BVU is VFR, wind from the south (180°) at 7 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: 5 flights in the DOT's last twelve reported months, the route's page.

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.
