Syracuse Hancock International to Nantucket Memorial SYR → ACK
291 nautical miles (335 statute miles) east on a straight line, true course 110°, about 123° magnetic at the departure end (variation 13W). At 120 knots that is 1 h 48 min at the quickest height in today's winds (34,000 ft, a 41-knot tailwind), arriving about 6:47 am EDT (10:47 UTC), after sunset at the destination. 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.

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 E27E: thunderstorms (a convective SIGMET) up to 35,000 ft, moving from the southwest at 20 knots, until 5:55 am EDT (09:55 UTC). Over the last 29 nm of the route.

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 SYR.

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.

Sunset at SYR 6:27 pm EDT (22:27 UTC), at ACK 6:04 pm EDT (22:04 UTC) (civil twilight ends 6:32 pm EDT (22:32 UTC)). At 120 knots the arrival at ACK is before sunrise there (6:48 am EDT (10:48 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
