Frederick W Smith Intl/Memphis Airport to General Edward Lawrence Logan International MEM → BOS
989 nautical miles (1,138 statute miles) northeast on a straight line, true course 058°, about 059° magnetic at the departure end (variation 1W). At 120 knots that is 6 h 25 min at the quickest height in today's winds (34,000 ft, a 34-knot tailwind), arriving about 7:40 am EDT (11:40 UTC). Right now MEM is VFR, wind from the south (180°) at 7 knots; BOS is IFR, wind from the north-northeast (030°) at 11 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: 1,986 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 11 forecast points nearest it (MEM, BNA, LOU, CRW, EKN, AGC, PSB, AVP, JFK, BDL, BOS). 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.
