Harrisburg International to Myrtle Beach International MDT → MYR
405 nautical miles (466 statute miles) south on a straight line, true course 196°, about 207° magnetic at the departure end (variation 11W). At 120 knots that is 2 h 52 min at the quickest height in today's winds (4,500 ft, a 21-knot tailwind), arriving about 8:37 am EDT (12:37 UTC). 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: 141 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.
