Centennial Airport to Harry Reid International APA → LAS
531 nautical miles (611 statute miles) west on a straight line, true course 250°, about 242° magnetic at the departure end (variation 8E). At 120 knots that is 5 h 35 min at the quickest height in today's winds (8,500 ft, a 25-knot headwind), arriving about 2:13 am PDT (09:13 UTC), after sunset at the destination. Right now APA is VFR, wind from the south-southwest (200°) at 21 knots, gusting to 34; 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: 509 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.
