Daniel K Inouye International to Boise Air Trml/Gowen Field HNL → BOI
2,462 nautical miles (2,834 statute miles) northeast on a straight line, true course 047°, about 036° magnetic at the departure end (variation 11E). At 120 knots that is 21 h 25 min at the quickest height in today's winds (3,500 ft, a 5-knot headwind), arriving about 7:04 pm MDT (01:04 UTC). Right now HNL is VFR, wind from the northeast (040°) at 8 knots; BOI is VFR, wind variable 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: 2 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the route from 1944 to 2333 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 1944 to 2064 nm out.
- AIRMET ZULU 2C: moderate icing up to 20,000 ft. Near the route, 2303 nm along the route.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the last 20 nm of the route.
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 HNL.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- PC12 at 6,500 ft, 48 nm southeast, 3:09 pm HST (01:09 UTC): no turbulence, clear from 6,500 ft to 60,000 ft. At the departure end, 48 nm southeast of the line.

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 3 forecast points nearest it (HNL, OGG, ITO). 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.
