Tri-Cities Airport to Salt Lake City International TRI → SLC
1,404 nautical miles (1,616 statute miles) west on a straight line, true course 290°, about 297° magnetic at the departure end (variation 7W). At 120 knots that is 13 h 22 min at the quickest height in today's winds (10,500 ft, a 15-knot headwind), arriving about 4:02 pm MDT (22:02 UTC). 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, fog). Over the first 199 nm of the route.
- AIRMET TANGO 5W: moderate turbulence above 18,000 ft (due to mountain wave) from 29,000 ft to 40,000 ft. Over the first 0 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 90 nm of the route.
- AIRMET TANGO 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 478 to 936 nm out.
- AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 42,000 ft. Over the route from 1016 to 1364 nm out.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 388 nm of the route.
- AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 1075 to 1235 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 279 nm of the route.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the last 249 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 TRI.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 13 forecast points nearest it (TRI, TYS, LOU, EVV, STL, COU, MKC, SLN, GRI, GLD, DEN, RKS, SLC). 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.
