Dona Ana County International Jetport to Seattle-Tacoma International DNA → SEA
1,176 nautical miles (1,353 statute miles) northwest on a straight line, true course 327°, about 316° magnetic at the departure end (variation 11E). At 120 knots that is 9 h 11 min at the quickest height in today's winds (18,000 ft, a 8-knot tailwind), arriving about 9:14 am PDT (16:14 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.

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 DNA.

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 10 forecast points nearest it (ELP, ABQ, FMN, BCE, ELY, BAM, BOI, 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.
