Salt Lake City International to Yellowstone Regional SLC → COD
259 nautical miles (298 statute miles) northeast on a straight line, true course 029°, about 018° magnetic at the departure end (variation 11E). At 120 knots that is 1 h 23 min at the quickest height in today's winds (30,000 ft, a 67-knot tailwind), arriving about 11:46 am MDT (17:46 UTC). Right now SLC is VFR, wind from the west-southwest (250°) at 6 knots; COD is IFR, wind from the northeast (050°) at 7 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.

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 (SLC, LND, BIL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
