Myrtle Beach International to Niagara Falls International MYR → IAG
566 nautical miles (651 statute miles) north on a straight line, true course 360°, about 009° magnetic at the departure end (variation 9W). At 120 knots that is 4 h 13 min at the quickest height in today's winds (34,000 ft, a 14-knot tailwind), arriving about 3:46 am EDT (07:46 UTC), after sunset at the destination. Right now MYR is VFR, wind from the southwest (230°) at 10 knots, gusting to 14; IAG is VFR, wind calm. 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: 79 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 7 forecast points nearest it (FLO, RDU, ROA, EKN, AGC, PSB, BUF). A plus sign is a headwind, a minus sign a tailwind.

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.
