How the Boston to Porto route actually runs
Pro Flight Search records official board updates for nonstop BOS to OPO 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.

BOS to OPO questions
Is BOS–OPO running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from BOS to OPO?
Great-circle distance is 5,048 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 386–463 min gate-to-gate on this route.
How often does BOS–OPO fly?
TAP-Air Portugal runs the route with about 4 flights a week (sun, tue, wed, sat). 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 BOS and arrival-side delay at OPO, 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.
