Chicago/Rockford International to Salt Lake City International RFD → SLC

1,029 nautical miles (1,185 statute miles) west on a straight line, true course 273°, about 276° magnetic at the departure end (variation 3W). At 120 knots that is 8 h 57 min at the quickest height in today's winds (4,500 ft, a 5-knot headwind), arriving about 4:44 am MDT (10:44 UTC), after sunset at the destination. Right now RFD is VFR, wind calm; SLC is VFR, wind from the east-northeast (070°) at 3 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: 158 flights in the DOT's last twelve reported months, the route's page.

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.
