Piedmont Triad International to Laredo International GSO → LRD
1,118 nautical miles (1,286 statute miles) west on a straight line, true course 248°, about 256° magnetic at the departure end (variation 8W). At 120 knots that is 9 h 38 min at the quickest height in today's winds (39,000 ft, a 4-knot headwind), arriving about 12:23 pm CDT (17:23 UTC). 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: 8 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
- AIRMET TANGO 5W: moderate turbulence below 18,000 ft (due to mountain wave) up to 10,000 ft, from 2:00 am EDT (06:00 UTC). Over the first 220 nm of the route.
- AIRMET TANGO 5W: moderate turbulence above 18,000 ft (due to mountain wave) from 29,000 ft to 40,000 ft, from 2:00 am EDT (06:00 UTC). Over the route from 70 to 180 nm out.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 2:00 am EDT (06:00 UTC). Over the route from 160 to 200 nm out.
- AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 2:00 am EDT (06:00 UTC). Near the route, 309 nm along the route.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from GSO.

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 10 forecast points nearest it (RDU, GSP, ATL, BHM, JAN, LCH, HOU, PSX, CRP, LRD). 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.

Sunset at GSO 6:48 pm EDT (22:48 UTC), at LRD 7:11 pm CDT (00:11 UTC) (civil twilight ends 7:34 pm CDT (00:34 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.
