The Eastern Iowa Airport to Idaho Falls Regional CID → IDA
901 nautical miles (1,037 statute miles) west on a straight line, true course 283°, about 281° magnetic at the departure end (variation 2E). At 120 knots that is 8 h 07 min at the quickest height in today's winds (4,500 ft, a 9-knot headwind), arriving about 8:48 am MDT (14:48 UTC). Right now CID is VFR, wind from the south (180°) at 6 knots; IDA is marginal VFR, wind calm. 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.

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.

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.
