Seattle-Tacoma International to Tucson International SEA → TUS
1,057 nautical miles (1,216 statute miles) southeast on a straight line, true course 146°, about 130° magnetic at the departure end (variation 16E). At 120 knots that is 8 h 40 min at the quickest height in today's winds (5,500 ft, a 2-knot tailwind), arriving about 10:43 am MST (17:43 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: 2,136 flights in the DOT's last twelve reported months, the route's page.

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