Lubbock Preston Smith International to Boise Air Trml/Gowen Field LBB → BOI

898 nautical miles (1,033 statute miles) northwest on a straight line, true course 316°, about 310° magnetic at the departure end (variation 6E). At 120 knots that is 6 h 58 min at the quickest height in today's winds (24,000 ft, a 9-knot tailwind), arriving about 3:10 pm MDT (21:10 UTC). Right now LBB is VFR, wind from the south (170°) at 8 knots; BOI is VFR, wind from the northwest (310°) at 4 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 14:00–21:00 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 (LBB, TCC, ALS, GJT, SLC, PIH, BOI). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
