General Edward Lawrence Logan International to Frederick W Smith Intl/Memphis Airport BOS → MEM
989 nautical miles (1,138 statute miles) west on a straight line, true course 250°, about 265° magnetic at the departure end (variation 15W). At 120 knots that is 8 h 19 min at the quickest height in today's winds (4,500 ft, a 1-knot headwind), arriving about 6:45 am CDT (11:45 UTC), after sunset at the destination. Right now BOS is IFR, wind from the east-northeast (060°) at 12 knots; MEM is VFR, wind from the south (170°) at 3 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.

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 10 forecast points nearest it (BOS, BDL, AVP, PSB, EKN, CRW, CVG, LOU, BNA, MEM). 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.
