Patrick Leahy Burlington International to Chicago O'Hare International BTV → ORD
662 nautical miles (761 statute miles) west on a straight line, true course 262°, about 277° magnetic at the departure end (variation 15W). At 120 knots that is 5 h 39 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 2:30 am CDT (07:30 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: 2,455 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 ZULU 1C: moderate icing up to 22,000 ft. Over the first 109 nm of the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the first 128 nm of the route.
- AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 13,000 ft. Over the first 69 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 20 to 79 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 415 to 454 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 BTV.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- DH8D at 19,000 ft, 48 nm south, 7:35 pm EDT (23:35 UTC): moderate chop turbulence, remarks: zob. 207 nm along the route, 48 nm south of the line.

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 6 forecast points nearest it (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.
