Daniel K Inouye International to Chicago Midway International HNL → MDW
3,690 nautical miles (4,246 statute miles) northeast on a straight line, true course 053°, about 042° magnetic at the departure end (variation 11E). At 120 knots that is 30 h 45 min at the quickest height in today's winds (7,500 ft, no wind along the track), arriving about 5:24 am CDT (10:24 UTC), after sunset at the destination. 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 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 3 forecast points nearest it (HNL, OGG, ITO). 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.
