Yakima Air Trml/Mcallister Field to San Angelo Rgnl/Mathis Field YKM → SJT
1,300 nautical miles (1,496 statute miles) southeast on a straight line, true course 128°, about 112° magnetic at the departure end (variation 16E). At 120 knots that is 10 h at the quickest height in today's winds (34,000 ft, a 10-knot tailwind), arriving about 5:20 pm CDT (22:20 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.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed
The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 11 forecast points nearest it (YKM, LWS, BOI, PIH, SLC, GJT, FMN, ALS, TCC, LBB, ABI). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
