Chicago O'Hare International to Jackson Hole Airport ORD → JAC
1,007 nautical miles (1,159 statute miles) west on a straight line, true course 283°, about 286° magnetic at the departure end (variation 3W). At 120 knots that is 9 h 52 min at the quickest height in today's winds (8,500 ft, a 18-knot headwind), arriving about 3:20 pm MDT (21:20 UTC). Right now ORD is VFR, wind from the south-southwest (210°) at 8 knots; JAC is VFR, wind from the east-northeast (070°) at 3 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: 1,596 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 150 to 389 nm out.
- AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 429 to 908 nm out.
- AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 738 to 768 nm out.
- AIRMET TANGO 4W: moderate turbulence above 18,000 ft (due to mountain wave) from 34,000 ft to 43,000 ft. Near the route, 808 nm along the route.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 190 nm of the route.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the last 140 nm of the route.
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 ORD.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- BE9L at 17,000 ft, 37 nm south, 4:42 am CDT (09:42 UTC): light rime icing from 15,000 ft to 17,000 ft, 0 °C, remarks: zdvwc. 838 nm along the route, 37 nm south of the line.

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 westbound cruising heights for this course (VFR: even 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 (JOT, DBQ, MCW, FSD, ONL, PIR, RAP, LND). 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.
