General Edward Lawrence Logan International to Daniel K Inouye International BOS → HNL

4,420 nautical miles (5,087 statute miles) west on a straight line, true course 284°, about 299° magnetic at the departure end (variation 15W). At 120 knots that is 32 h 59 min at the quickest height in today's winds (24,000 ft, a 14-knot tailwind), arriving about 12:09 am HST (10:09 UTC), after sunset at the destination. Right now BOS is marginal VFR, wind from the east (080°) at 8 knots; HNL is VFR, 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: 134 flights in the DOT's last twelve reported months, the route's page.

AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the route from 1676 to 2115 nm out.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 25,000 ft to 39,000 ft. Over the route from 2355 to 2484 nm out.
AIRMET TANGO 2W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 2375 to 2484 nm out.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from BOS.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed

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 18 forecast points nearest it (BOS, BDL, ALB, SYR, BUF, TVC, GRB, LSE, MSP, FSD, PIR, RAP, LND, PIH, BAM, RNO, RBL, FOT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
