Ellison Onizuka Kona International AT Keahole to Phoenix Sky Harbor International KOA → PHX
2,482 nautical miles (2,856 statute miles) northeast on a straight line, true course 061°, about 050° magnetic at the departure end (variation 11E). At 120 knots that is 20 h 21 min at the quickest height in today's winds (9,500 ft, a 2-knot tailwind), arriving about 3:30 pm MST (22:30 UTC). 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: 762 flights in the DOT's last twelve reported months, the route's page.

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.
