William P Hobby Airport to Portland International HOU → PDX
1,601 nautical miles (1,842 statute miles) northwest on a straight line, true course 314°, about 311° magnetic at the departure end (variation 3E). At 120 knots that is 12 h 42 min at the quickest height in today's winds (4,500 ft, a 6-knot tailwind), arriving about 8:23 am PDT (15:23 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: 6 flights in the DOT's last twelve reported months, the route's page.

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 14 forecast points nearest it (HOU, CLL, DAL, ABI, LBB, AMA, TCC, ALS, GJT, SLC, PIH, BOI, RDM, PDX). 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.
