Seattle-Tacoma International to Dona Ana County International Jetport SEA → DNA

1,176 nautical miles (1,353 statute miles) southeast on a straight line, true course 137°, about 121° magnetic at the departure end (variation 16E). At 120 knots that is 9 h 48 min at the quickest height in today's winds (39,000 ft, no wind along the track), arriving about 5:26 am MDT (11:26 UTC), after sunset at the destination. Right now SEA is VFR, wind from the north (350°) at 11 knots; DNA is VFR, wind from the west-northwest (300°) 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: 1 flights in the DOT's last twelve reported months, the route's page.

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 10 forecast points nearest it (SEA, YKM, RDM, BOI, BAM, ELY, BCE, FMN, ABQ, ELP). 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.
