Martha'S Vineyard Airport to Chautauqua County/Jamestown MVY → JHW
390 nautical miles (448 statute miles) west on a straight line, true course 280°, about 295° magnetic at the departure end (variation 15W). At 120 knots that is 3 h 20 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 8:22 am EDT (12:22 UTC). Right now MVY is IFR, wind from the north-northeast (030°) at 15 knots, gusting to 27; JHW is IFR, wind from the north-northwest (330°) at 5 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: 4 flights in the DOT's last twelve reported months, the route's page.

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.
