Tucson International to Seattle-Tacoma International TUS → SEA
1,057 nautical miles (1,216 statute miles) northwest on a straight line, true course 334°, about 325° magnetic at the departure end (variation 9E). At 120 knots that is 8 h 12 min at the quickest height in today's winds (39,000 ft, a 9-knot tailwind), arriving about 7:27 am PDT (14:27 UTC). Right now TUS is VFR, wind calm; SEA is VFR, wind from the east-southeast (110°) 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: 2,136 flights in the DOT's last twelve reported months, the route's page.

- AIRMET TANGO 2W: moderate turbulence above 18,000 ft from 35,000 ft to 45,000 ft. Over the route from 90 to 259 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 110 to 868 nm out.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the route from 160 to 489 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 249 to 279 nm out.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 259 to 608 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the route from 648 to 668 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the last 289 nm of the route.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 808 to 907 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 TUS.

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 11 forecast points nearest it (TUS, PHX, PRC, LAS, ELY, BAM, BOI, LKV, RDM, YKM, SEA). 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.
