Ontario International to Des Moines International ONT → DSM
1,216 nautical miles (1,400 statute miles) northeast on a straight line, true course 061°, about 049° magnetic at the departure end (variation 12E). At 120 knots that is 6 h 20 min at the quickest height in today's winds (34,000 ft, a 72-knot tailwind), arriving about 3:19 pm CDT (20:19 UTC). Right now ONT is marginal VFR, wind from the west (270°) at 9 knots; DSM is VFR, wind from the south-southwest (200°) at 11 knots, gusting to 19. 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.

- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 189 to 568 nm out.
- AIRMET SIERRA 2E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 209 to 309 nm out.
- AIRMET TANGO 4W: moderate turbulence above 18,000 ft (due to mountain wave) from 34,000 ft to 43,000 ft. Over the route from 259 to 788 nm out.

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 (ONT, LAS, PRC, BCE, FMN, ALS, PUB, GLD, GRI, OMA, DSM). 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.
