Morristown Municipal to Key West International MMU → EYW
1,042 nautical miles (1,200 statute miles) southwest on a straight line, true course 203°, about 216° magnetic at the departure end (variation 13W). At 120 knots that is 8 h 20 min at the quickest height in today's winds (4,500 ft, a 5-knot tailwind), arriving about 3:00 pm EDT (19:00 UTC). Right now MMU is marginal VFR, wind from the north (350°) at 5 knots; EYW is VFR, wind from the northeast (050°) 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.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- SIGMET E33E: thunderstorms (a convective SIGMET) up to 45,000 ft, moving from the west at 20 knots, until 7:55 am EDT (11:55 UTC). Near the route, 814 nm along the route.

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 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 9 forecast points nearest it (JFK, ACY, ORF, ILM, CHS, JAX, MLB, MIA, 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.
