San Francisco International to William P Hobby Airport SFO → HOU
1,431 nautical miles (1,646 statute miles) east on a straight line, true course 101°, about 087° magnetic at the departure end (variation 14E). At 120 knots that is 9 h 32 min at the quickest height in today's winds (34,000 ft, a 30-knot tailwind), arriving about 6:40 pm CDT (23:40 UTC). Right now SFO is VFR, wind from the west (280°) at 5 knots; HOU is VFR, wind from the southeast (130°) at 8 knots. 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: 5 flights in the DOT's last twelve reported months, the route's page.

- AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 219 to 308 nm out.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Near the route, 378 nm along the route.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 417 to 656 nm out.
- AIRMET SIERRA 2E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 427 to 536 nm out.
- AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 467 to 735 nm out.

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 eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 12 forecast points nearest it (SFO, FAT, BIH, LAS, PRC, ABQ, ROW, INK, ABI, SAT, CLL, HOU). 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.
