Greenville Spartanburg International to Harry Reid International GSP → LAS

1,604 nautical miles (1,846 statute miles) west on a straight line, true course 282°, about 288° magnetic at the departure end (variation 6W). At 120 knots that is 14 h 43 min at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 9:27 am PDT (16:27 UTC). Right now GSP is VFR, wind from the west-southwest (240°) at 8 knots; LAS is VFR, wind from the south (190°) at 12 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.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from GSP.

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 15 forecast points nearest it (GSP, TYS, BNA, MEM, LIT, SGF, TUL, ICT, GAG, AMA, TCC, ALS, FMN, BCE, LAS). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
