Shreveport Regional to Aspen-Pitkin County/Sardy Field SHV → ASE
753 nautical miles (866 statute miles) northwest on a straight line, true course 306°, about 304° magnetic at the departure end (variation 2E). At 120 knots that is 6 h 20 min at the quickest height in today's winds (4,500 ft, a 1-knot headwind), arriving about 8:00 am MDT (14:00 UTC). Right now SHV is VFR, wind from the south (190°) at 7 knots; ASE is VFR, wind variable at 3 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: 1 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 (SHV, DAL, OKC, GAG, GCK, PUB, GJT). 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.
