Spokane International to Salt Lake City International GEG → SLC
474 nautical miles (546 statute miles) southeast on a straight line, true course 148°, about 134° magnetic at the departure end (variation 14E). At 120 knots that is 3 h 48 min at the quickest height in today's winds (5,500 ft, a 5-knot tailwind), arriving about 11:38 pm MDT (05:38 UTC), after sunset at the destination. Right now GEG is VFR, wind from the northeast (040°) at 15 knots; SLC is VFR, wind from the east-northeast (070°) at 3 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: 3,326 flights in the DOT's last twelve reported months, the route's page.

- AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the last 346 nm of the route.
- 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 route from 188 to 287 nm out.
- AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the last 277 nm of the route.

- 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 last 0 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 GEG.

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 eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 5 forecast points nearest it (GEG, LWS, BOI, PIH, SLC). 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.
