Cyril E King Airport to Austin-Bergstrom International STT → AUS

1,917 nautical miles (2,206 statute miles) northwest on a straight line, true course 298°, about 311° magnetic at the departure end (variation 13W). At 120 knots that is 15 h 43 min at the quickest height in today's winds (4,500 ft, a 2-knot tailwind), arriving about 12:41 am CDT (05:41 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 return flight

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 STT.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

Not fetched just now.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 9 forecast points nearest it (MIA, EYW, PIE, MOB, MSY, LCH, HOU, CLL, SAT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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

  • 6/2698 VIEQUES, PR, Monday, January 19, 2026 through Friday, December 18, 2026 UTC 16 nm from the route, at the departure end · a hazard on the ground (fire-fighting, a chemical spill, rescue work) · until 18 December · ZSU

Daylight

Sunset at STT 5:59 pm AST (21:59 UTC), at AUS 7:02 pm CDT (00:02 UTC) (civil twilight ends 7:26 pm CDT (00:26 UTC)). At 120 knots the arrival at AUS is before sunrise there (7:31 am CDT (12:31 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.
