OPO to BOS questions

Is OPO–BOS running on time right now?

Smooth skies ahead. The departure side at OPO is the weaker end, route health score 90/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from OPO to BOS?

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 OPO–BOS fly?

TAP Air Portugal runs the route with about 4 flights a week (sun, mon, 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 OPO and arrival-side delay at BOS, 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.
