Rapid City Regional to Harry Reid International RAP → LAS
732 nautical miles (842 statute miles) southwest on a straight line, true course 233°, about 225° magnetic at the departure end (variation 8E). At 120 knots that is 8 h 08 min at the quickest height in today's winds (8,500 ft, a 30-knot headwind), arriving about 4:32 am PDT (11:32 UTC), after sunset at the destination. Right now RAP is low IFR, wind from the east-southeast (110°) at 4 knots; LAS is VFR, wind from the south (190°) at 10 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: 222 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 02:00–09:00 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 7 forecast points nearest it (RAP, BFF, LND, RKS, GJT, BCE, LAS). A plus sign is a headwind, a minus sign a tailwind.

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.
