MC Allen International to Salt Lake City International MFE → SLC
1,112 nautical miles (1,280 statute miles) northwest on a straight line, true course 326°, about 322° magnetic at the departure end (variation 4E). At 120 knots that is 8 h at the quickest height in today's winds (4,500 ft, a 19-knot tailwind), arriving about 4:40 am MDT (10:40 UTC), after sunset at the destination. 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 westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 9 forecast points nearest it (BRO, LRD, DRT, INK, ROW, ABQ, FMN, GJT, SLC). A plus sign is a headwind, a minus sign a tailwind.

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.

Daylight
Sunset at MFE 7:08 pm CDT (00:08 UTC), at SLC 6:52 pm MDT (00:52 UTC) (civil twilight ends 7:19 pm MDT (01:19 UTC)). At 120 knots the arrival at SLC is before sunrise there (7:35 am MDT (13:35 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
