Ted Stevens Anchorage International to San Antonio International ANC → SAT

2,771 nautical miles (3,188 statute miles) east on a straight line, true course 109°, about 093° magnetic at the departure end (variation 16E). At 120 knots that is 16 h 18 min at the quickest height in today's winds (34,000 ft, a 50-knot tailwind), arriving about 1:57 pm CDT (18:57 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: 3 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 ANC.

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.
