William P Hobby Airport to Portland International Jetport HOU → PWM
1,458 nautical miles (1,678 statute miles) northeast on a straight line, true course 048°, about 045° magnetic at the departure end (variation 3E). At 120 knots that is 11 h 34 min at the quickest height in today's winds (39,000 ft, a 6-knot tailwind), arriving about 5:17 pm EDT (21:17 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: 1 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 SIERRA 1E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, mist, fog). Near the route, 120 nm along the route.
- AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist, fog). Over the last 929 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the route from 689 to 1378 nm out.
- AIRMET TANGO 3W: moderate turbulence below 18,000 ft (due to mountain wave) up to 6,000 ft. Over the route from 979 to 1039 nm out.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 33,000 ft. Over the last 340 nm of the route.
- AIRMET ZULU 1C: moderate icing from 12,000 ft to 24,000 ft. Over the last 90 nm of 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 HOU.

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 17 forecast points nearest it (HOU, LCH, SHV, JAN, MEM, HSV, BNA, TYS, TRI, CRW, EKN, AGC, PSB, AVP, ALB, BOS, PWM). 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.
