Ellison Onizuka Kona International AT Keahole to Ontario International KOA → ONT
2,214 nautical miles (2,548 statute miles) northeast on a straight line, true course 059°, about 048° magnetic at the departure end (variation 11E). At 120 knots that is 18 h 18 min at the quickest height in today's winds (7,500 ft, a 1-knot tailwind), arriving about 11:07 am PDT (18:07 UTC). Right now KOA is VFR, wind from the west-southwest (250°) at 12 knots; ONT is VFR, wind from the west-southwest (250°) at 11 knots, gusting to 18. 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: 657 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 SIERRA 6E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 30 nm of the route.
- AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 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 KOA.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B737 at 14,000 ft, 20 nm north, 11:54 am HST (21:54 UTC): moderate turbulence. At the destination end, 20 nm north of the line.

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 2 forecast points nearest it (KOA, ITO). 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.
