Frederick W Smith Intl/Memphis Airport to Key West International MEM → EYW
761 nautical miles (875 statute miles) southeast on a straight line, true course 144°, about 145° magnetic at the departure end (variation 1W). At 120 knots that is 5 h 04 min at the quickest height in today's winds (34,000 ft, a 30-knot tailwind), arriving about 1:24 pm EDT (17:24 UTC). Right now MEM is VFR, wind calm; EYW is VFR, wind from the northeast (040°) at 4 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 08:00–15:00 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 6 forecast points nearest it (MEM, BHM, MGM, TLH, PIE, EYW). 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.
