Phoenix Sky Harbor International to St. Louis Lambert International PHX → STL
1,094 nautical miles (1,259 statute miles) northeast on a straight line, true course 067°, about 055° magnetic at the departure end (variation 12E). At 120 knots that is 5 h 57 min at the quickest height in today's winds (34,000 ft, a 64-knot tailwind), arriving about 6:40 am CDT (11:40 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: 4,624 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.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- SIGMET 7C: thunderstorms (a convective SIGMET) up to 34,000 ft, moving from the southwest at 40 knots, until 11:55 pm MST (06:55 UTC). Over the route from 328 to 497 nm out.

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.

Temporary flight restrictions on the line or within 25 nm of it
No temporary flight restriction on or near this route right now.
Daylight
Sunset at PHX 5:58 pm MST (00:58 UTC), at STL 6:27 pm CDT (23:27 UTC) (civil twilight ends 6:54 pm CDT (23:54 UTC)). At 120 knots the arrival at STL is before sunrise there (7:07 am CDT (12:07 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.
