PWM to SFO questions
Is PWM–SFO running on time right now?
Smooth skies ahead. The departure side at PWM is the weaker end, route health score 94/100. The airports section above carries the live status and delay window at both ends.
Morning or evening flight on PWM–SFO?
Operators schedule morning departures around 07:30 from PWM. Earlier flights typically land before destination-airport delays accumulate later in the day; check the SFO delay card to confirm conditions when you'd arrive.
How long is the flight from PWM to SFO?
Great-circle distance is 4,372 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 339–405 min gate-to-gate on this route.
How often does PWM–SFO fly?
United Airlines runs the route with about 2 flights a week (sun). Since one carrier owns the route, a single disruption tends to ripple through the day.
