Bangor International to Chicago O'Hare International BGR → ORD

848 nautical miles (975 statute miles) west on a straight line, true course 265°, about 281° magnetic at the departure end (variation 16W). At 120 knots that is 7 h 26 min at the quickest height in today's winds (4,500 ft, a 6-knot headwind), arriving about 3:00 am CDT (08:00 UTC), after sunset at the destination. Right now BGR is VFR, wind from the south (190°) at 7 knots; ORD is VFR, wind from the south (170°) at 6 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: 1,373 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the first 319 nm of the route.
AIRMET TANGO 6W: moderate turbulence below 18,000 ft up to 7,000 ft. Over the first 40 nm of the route.
AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the route from 50 to 309 nm out.
AIRMET ZULU 1C: moderate icing up to 24,000 ft. Over the route from 80 to 319 nm out.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 219 to 259 nm out.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 598 to 658 nm out.

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 BGR.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 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 (BGR, BML, ALB, SYR, BUF, CLE, MKG, JOT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
