Boise Air Trml/Gowen Field to Minneapolis-St Paul Intl/Wold-Chamberlain Airport BOI → MSP
989 nautical miles (1,139 statute miles) east on a straight line, true course 077°, about 064° magnetic at the departure end (variation 13E). At 120 knots that is 5 h 47 min at the quickest height in today's winds (39,000 ft, a 51-knot tailwind), arriving about 12:53 pm CDT (17:53 UTC). Right now BOI is VFR, wind from the west-northwest (300°) at 7 knots; MSP is VFR, wind from the southwest (220°) 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: 1,604 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
- SIGMET C18C: thunderstorms (a convective SIGMET) up to 36,000 ft, moving from the southwest at 40 knots, until 7:55 am MDT (13:55 UTC). Near the route, 690 nm along the route.

- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 40 to 460 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 60 to 400 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 BOI.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
No pilot reports within 50 nautical miles of the line in the last three hours.

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.
