Tucson International to Boise Air Trml/Gowen Field TUS → BOI
731 nautical miles (841 statute miles) north on a straight line, true course 342°, about 333° magnetic at the departure end (variation 9E). At 120 knots that is 4 h 38 min at the quickest height in today's winds (30,000 ft, a 38-knot tailwind), arriving about 6:39 am MDT (12:39 UTC), after sunset at the destination. Right now TUS is VFR, wind from the south-southeast (150°) at 4 knots; BOI is VFR, wind from the west-northwest (300°) at 8 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: 5 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 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 79 to 662 nm out.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the route from 158 to 514 nm out.
- AIRMET SIERRA 2E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 178 to 287 nm out.
- AIRMET TANGO 2W: moderate turbulence above 18,000 ft from 35,000 ft to 45,000 ft. Over the route from 207 to 336 nm out.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 287 to 672 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the last 79 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 TUS.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B737 at 14,000 ft, 19 nm west, 10:15 pm MST (05:15 UTC): moderate turbulence, remarks: during the descent through clouds. 119 nm along the route, 19 nm west of the line.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 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 7 forecast points nearest it (TUS, PHX, PRC, BCE, ELY, BAM, BOI). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
