Dubois Municipal to Chicago O'Hare International DUB → ORD
962 nautical miles (1,107 statute miles) east on a straight line, true course 088°, about 078° magnetic at the departure end (variation 10E). At 120 knots that is 5 h 30 min at the quickest height in today's winds (39,000 ft, a 55-knot tailwind), arriving about 8:11 am CDT (13:11 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: 2,374 flights in the DOT's last twelve reported months, the route's page.

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 8 forecast points nearest it (LND, RAP, PIR, ONL, FSD, MCW, DBQ, JOT). 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.
