Harry Reid International to Ellison Onizuka Kona International AT Keahole LAS → KOA
2,359 nautical miles (2,715 statute miles) west on a straight line, true course 257°, about 246° magnetic at the departure end (variation 11E). At 120 knots that is 17 h 36 min at the quickest height in today's winds (24,000 ft, a 14-knot tailwind), arriving about 10:12 am HST (20:12 UTC). Right now LAS is VFR, wind from the south-southeast (150°) at 8 knots, gusting to 21; KOA is VFR, wind from the west (260°) at 10 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: 731 flights in the DOT's last twelve reported months, the route's page.
The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words
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 ZULU 3C: moderate icing up to 22,000 ft. Over the first 80 nm of the route.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the first 10 nm of the route.
- AIRMET SIERRA 6E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 240 to 260 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 LAS.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- E145 at 15,000 ft, 22 nm south, 6:45 pm PDT (01:45 UTC): moderate chop turbulence, light rime icing, -9 °C. At the departure end, 22 nm south 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 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 4 forecast points nearest it (LAS, WJF, SBA, SFO). 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.
