Luis Munoz Marin International to General Mitchell International SJU → MKE

1,843 nautical miles (2,121 statute miles) northwest on a straight line, true course 328°, about 339° magnetic at the departure end (variation 11W). At 120 knots that is 13 h 58 min at the quickest height in today's winds (34,000 ft, a 12-knot tailwind), arriving about 10:11 am CDT (15:11 UTC). Right now SJU is VFR, wind from the east-southeast (110°) at 4 knots; MKE is VFR, wind from the south-southeast (160°) 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: 2 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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

AIRMET TANGO 5W: moderate turbulence below 18,000 ft (due to mountain wave) up to 7,000 ft. Over the route from 1315 to 1405 nm out.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 1315 to 1475 nm out.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 1365 to 1624 nm out.

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 SJU.

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 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 (MIA, MLB, ILM, RDU, ROA, CRW, CMH, FWA, MKG). 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.
