How the Atlanta to Portland route actually runs
Pro Flight Search records official board updates for nonstop ATL to PWM flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

ATL to PWM questions
Is ATL–PWM running on time right now?
Mostly on schedule. The departure side at ATL is the weaker end, route health score 80/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ATL to PWM?
Great-circle distance is 1,652 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 147–172 min gate-to-gate on this route.
How often does ATL–PWM fly?
Delta Air Lines runs the route with about 14 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
What does the route health score measure?
A blend of departure-side delay at ATL and arrival-side delay at PWM, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
