Idaho Falls Regional to Fresno Yosemite International IDA → FAT
535 nautical miles (616 statute miles) southwest on a straight line, true course 223°, about 211° magnetic at the departure end (variation 12E). At 120 knots that is 4 h 23 min at the quickest height in today's winds (4,500 ft, a 2-knot tailwind), arriving about 6:22 am PDT (13:22 UTC), after sunset at the destination. Right now IDA is marginal VFR, wind calm; FAT is VFR, wind from the southeast (140°) at 13 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: 1 flights in the DOT's last twelve reported months, the route's page.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
