George Bush Intcntl/Houston Airport to Rick Husband Amarillo International IAH → AMA
450 nautical miles (518 statute miles) northwest on a straight line, true course 316°, about 313° magnetic at the departure end (variation 3E). At 120 knots that is 3 h 20 min at the quickest height in today's winds (4,500 ft, a 15-knot tailwind), arriving about 10:32 pm CDT (03:32 UTC), after sunset at the destination. Right now IAH is VFR, wind from the east-southeast (120°) at 11 knots; AMA is VFR, wind from the south (180°) at 19 knots, gusting to 25. 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: 1,990 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
No SIGMET or AIRMET covers any part of this route right now.
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 IAH.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- A320 at 24,000 ft, 2 nm south, 5:07 pm CDT (22:07 UTC): light chop turbulence, remarks: during the climb zhu. At the departure end, 2 nm south of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed
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 6 forecast points nearest it (CLL, DAL, ABI, SPS, LBB, AMA). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
