Portland International Jetport to San Francisco International PWM → SFO

2,361 nautical miles (2,717 statute miles) west on a straight line, true course 280°, about 295° magnetic at the departure end (variation 15W). At 120 knots that is 20 h 32 min at the quickest height in today's winds (4,500 ft, a 5-knot headwind), arriving about 3:39 pm PDT (22:39 UTC). Right now PWM is marginal VFR, wind calm; SFO is VFR, wind from the west-southwest (250°) at 9 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: 10 flights in the DOT's last twelve reported months, the route's page.

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 22 forecast points nearest it (PWM, BML, ALB, SYR, BUF, TVC, GRB, LSE, MSP, FSD, ONL, PIR, RAP, BFF, LND, RKS, SLC, ELY, BAM, RNO, SAC, SFO). A plus sign is a headwind, a minus sign a tailwind.

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.
