General Edward Lawrence Logan International to Scottsbluff/Western Nebraska Rgnl/Wm B Heilig Field BOS → BFF
1,443 nautical miles (1,660 statute miles) west on a straight line, true course 280°, about 295° magnetic at the departure end (variation 15W). At 120 knots that is 14 h 01 min at the quickest height in today's winds (6,500 ft, a 17-knot headwind), arriving about 10:06 pm MDT (04:06 UTC), after sunset at the destination. Right now BOS is IFR, wind from the north-northeast (020°) at 3 knots; BFF is low IFR, wind calm. 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 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 SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the first 20 nm of the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 40,000 ft. Over the first 119 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the route from 80 to 249 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 129 to 358 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 last 269 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 BOS.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

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 14 forecast points nearest it (BOS, BDL, ALB, SYR, BUF, CLE, MKG, GRB, DBQ, LSE, MCW, FSD, ONL, BFF). 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.
