Long Island Mac Arthur Airport to Minneapolis-St Paul Intl/Wold-Chamberlain Airport ISP → MSP
916 nautical miles (1,055 statute miles) west on a straight line, true course 292°, about 306° magnetic at the departure end (variation 14W). At 120 knots that is 8 h 24 min at the quickest height in today's winds (10,500 ft, a 11-knot headwind), arriving about 5:58 am CDT (10:58 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: 3 flights in the DOT's last twelve reported months, the route's page.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
