Idaho Falls Regional to Grand Junction Regional IDA → GJT
308 nautical miles (355 statute miles) southeast on a straight line, true course 148°, about 136° magnetic at the departure end (variation 12E). At 120 knots that is 2 h 37 min at the quickest height in today's winds (39,000 ft, a 2-knot headwind), arriving about 9:25 pm MDT (03:25 UTC), after sunset at the destination. Right now IDA is marginal VFR, wind from the north-northwest (340°) at 13 knots; GJT is VFR, wind from the south-southeast (160°) at 16 knots, gusting to 24. 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: 4 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 3 forecast points nearest it (PIH, RKS, GJT). 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.
