PWM to BWI questions

Is PWM–BWI running on time right now?

Smooth skies ahead. The departure side at PWM is the weaker end, route health score 92/100. The airports section above carries the live status and delay window at both ends.

Morning or evening flight on PWM–BWI?

Operators schedule morning departures around 05:20 and evening departures around 17:10 from PWM. Earlier flights typically land before destination-airport delays accumulate later in the day; check the BWI delay card to confirm conditions when you'd arrive.

How long is the flight from PWM to BWI?

Great-circle distance is 726 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 81–92 min gate-to-gate on this route.

How often does PWM–BWI fly?

Southwest Airlines runs the route with about 30 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
