Valley International to General Edward Lawrence Logan International HRL → BOS

1,627 nautical miles (1,873 statute miles) northeast on a straight line, true course 047°, about 044° magnetic at the departure end (variation 3E). At 120 knots that is 11 h 53 min at the quickest height in today's winds (34,000 ft, a 17-knot tailwind), arriving about 1:45 pm EDT (17:45 UTC). Right now HRL is VFR, wind from the southeast (140°) at 6 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: 2 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 19 forecast points nearest it (BRO, CRP, PSX, HOU, LCH, MSY, JAN, BHM, HSV, TYS, TRI, CRW, ROA, EKN, PSB, AVP, JFK, BDL, BOS). A plus sign is a headwind, a minus sign a tailwind.

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.
