St. George Regional to Chicago Midway International SGU → MDW

1,223 nautical miles (1,408 statute miles) east on a straight line, true course 069°, about 057° magnetic at the departure end (variation 12E). At 120 knots that is 6 h 37 min at the quickest height in today's winds (34,000 ft, a 65-knot tailwind), arriving about 12:46 pm CDT (17:46 UTC). Right now SGU is VFR, wind from the southeast (140°) at 9 knots; MDW is VFR, wind from the south-southwest (210°) at 7 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: 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 10 forecast points nearest it (BCE, GJT, DEN, GLD, GRI, OMA, DSM, BRL, DBQ, JOT). 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.
