Rick Husband Amarillo International to Boise Air Trml/Gowen Field AMA → BOI
837 nautical miles (964 statute miles) northwest on a straight line, true course 311°, about 303° magnetic at the departure end (variation 8E). At 120 knots that is 6 h 52 min at the quickest height in today's winds (24,000 ft, a 2-knot tailwind), arriving about 8:34 am MDT (14:34 UTC). 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: 2 flights in the DOT's last twelve reported months, the route's page.

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 (AMA, TCC, ALS, GJT, SLC, PIH, BOI). 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.
