Seattle-Tacoma International to Louis Armstrong New Orleans International SEA → MSY

1,811 nautical miles (2,084 statute miles) southeast on a straight line, true course 114°, about 098° magnetic at the departure end (variation 16E). At 120 knots that is 12 h 35 min at the quickest height in today's winds (39,000 ft, a 24-knot tailwind), arriving about 11:00 am CDT (16:00 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: 1,247 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 SEA.

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 16 forecast points nearest it (SEA, YKM, LWS, BOI, DLN, PIH, LND, RKS, DEN, GLD, GCK, GAG, OKC, FSM, SHV, MSY). 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.
