Morning or evening flight on PWM–IAD?

Operators schedule morning departures around 05:30 and evening departures around 19:35 from PWM. Earlier flights typically land before destination-airport delays accumulate later in the day; check the IAD delay card to confirm conditions when you'd arrive.

How long is the flight from PWM to IAD?

Great-circle distance is 793 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 86–98 min gate-to-gate on this route.

How often does PWM–IAD fly?

United Airlines runs the route with about 26 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
